How to Be a Good Undercover Agent—Crash Course once said:
“What is the first principle of being an undercover agent?
Trust, trust, and goddamn trust.”
Whether it was gathering intelligence, guiding the other party’s behavior, or withdrawing and running away at a critical moment, this entire series of operations had to be built on the foundation of trust.
Without trust, forget completing the mission—whether one could even keep one’s life was questionable.
So how could trust be established?
Su Bai summarized the contents of the book into a nine-character mantra:
Don’t cause trouble, dare to take responsibility, and know how to handle things.
Not causing trouble meant not creating problems for the undercover target.
This was the bottom line and could effectively lower negative evaluations.
Daring to take responsibility meant shouldering damage for the undercover target and, when necessary, taking the blame without hesitation, which could increase positive evaluations.
As for knowing how to handle things, that meant aggressively targeting the other party’s preferences and raising favorability (crossed out)—trust value.
This was the “essence” she had stayed up several nights summarizing, and the more she thought about it, the more reasonable it seemed.
Except… this set of tactics somehow felt strangely odd.
Where was the oddness?
She always felt that putting this theory into some galgame romance game and using it to conquer a girl would feel completely natural.
No, no, this was definitely an illusion.
She was only doing this to gain trust. How could it be the same?
Su Bai was randomly reviewing her plan in her head.
That’s right, I have an idea. ☝
“Classmate Jiang, let me help you tidy up.” Su Bai said, struck by sudden inspiration.
“Thank you for the kind intention. I arrived quite early and have already almost finished packing.” Jiang Yuelan smiled slightly.
Then she pointed at the pile of luggage behind Su Bai and said, “Rather than helping me, you haven’t even moved your own things yet. Let me help you instead.”
“I don’t need it. I can do it myself…”
Su Bai directly refused and went over wanting to pack on her own, yet Jiang Yuelan showed no intention of stopping and casually assisted from the side without caring.
Su Bai felt a bit of fear in her heart—after all, the other party was a suspected witch, so she did not dare to refuse firmly.
In the end she could only watch with open eyes as Jiang Yuelan took the main role while she stood to the side like a useless little wife, occasionally lending a hand.
Watching Jiang Yuelan busy herself inside and out while she herself could barely insert any help, the corner of Su Bai’s eye could not help twitching.
She felt that long-lost “egg-aching” sensation again—although she no longer had that kind of thing now (sad).
Setting aside Jiang Yuelan’s identity as a witch, Jiang Yuelan was actually treating her quite well?
Uh…
Probably, maybe, perhaps this also counted as achieving her goal? Getting along well with Jiang Yuelan…
…
My ass!
This is completely reversed.
Su Bai wailed in her heart.
The other party must definitely think of her as the kind of troublesome ghost who needed care everywhere.
The kindness Su Bai felt was perhaps some kind of disguise, only maintained so as not to expose her identity…
She was a witch.
Becoming a student and mixing into the campus, she must have secrets.
Who knew her true face?
Maybe one day the Witch-sama would settle accounts with her.
A scene popped into Su Bai’s mind: Jiang Yuelan revealing her true form, taking out a notebook and carefully listing every single thing Su Bai had done wrong, then using cruel methods to torment her one by one.
So, so terrifying QAQ.
At least the few witches she knew seemed like the type who would do something like that.
She absolutely could not let something like that happen!!
“Classmate Jiang, thank you so much for helping me. Let me treat you to dinner tonight. You can decide what to eat.”
Jiang Yuelan tilted her head, then the corners of her mouth lifted slightly as she said softly, “All right. There’s a Western restaurant outside the school gate that I’ve heard is pretty good. Let’s go together.”
My wallet hurts.
That shop clearly did not look cheap.
Although with her salary and savings she would not be unable to afford it, saying she did not feel the pain would be a lie.
“Sure, sure.” Su Bai put on a generous front.
What a joke. Even without association reimbursement, I would still have to treat this meal even if I had to take out a loan.
Not only is it repayment for the help just now, it is also an excellent opportunity to raise trust value.
In those film and television dramas, meal gatherings are the best places for talking business and getting things done.
If you’re going to do it, do it. Seize the opportunity.
Time quickly reached dinner time in the evening.
During the afternoon the two of them finished cleaning the dormitory and took turns showering.
Then Jiang Yuelan seemed tired.
After taking a shower she lay down on the bed and took a short nap.
Meanwhile Su Bai waited for the timing when Jiang Yuelan was about to finish washing and come out of the bathroom, then went downstairs to the small convenience store to buy some daily necessities that were inconvenient to carry.
When she returned she also knocked and asked whether clothes had been changed, avoiding the kind of dramatic and sensual plot that might otherwise occur.
It was simply because Su Bai clearly understood in her heart that on that day her three teammates had told many lies.
Yet there was one place where they had been right, and it was also the part that had scolded her awake:
She could not rely on this acquired female body to approach other girls without any restraint or scruples.
Even if the other party did not care,
even if the other party would never know her past,
even if this would bring trouble to her own life,
Su Bai still could not accept her own “crossing the line.”
Even if it could not be completely avoided, she at least had to try her best to have a clear conscience.
“Let’s go, Classmate Jiang.”
“Wow, the new clothes you changed into for the evening look really cool. They suit you especially well.”
Jiang Yuelan had changed outfits—from the simple sportswear of the afternoon into a matte black trench coat with a sharp, “girl-slaying” style.
Paired with skinny jeans, her entire person radiated a neat androgynous beauty, with several degrees more cool aloofness than in the afternoon.
This set looked especially suitable on Jiang Yuelan.
Praising once could both close the distance and raise trust value.
Not praising would be a waste.
And speaking honestly, this style was indeed cool and more in line with Su Bai’s first impression of Jiang Yuelan.
“As long as you like it.” The corners of Jiang Yuelan’s mouth curved as she took the lead in stepping forward.
“Let’s go, Classmate Xiao Bai.”
“Classmate Xiao Bai?” This form of address sounded both respectful and a bit intimate.
Su Bai froze for a moment.
“Ahem, calling me that is a bit strange.” She cleared her throat and waved her hand.
“How about you call me Su Bai from now on, or just Xiao Bai. A lot of people used to call me that. I don’t mind.”
“All right, Xiao Bai.” Jiang Yuelan agreed straightforwardly, yet her tone shifted.
“But in exchange, you can no longer call me Classmate Jiang either. Calling me Sister Yuelan or Sister Xiao Lan is fine.”
What the heck? Su Bai muttered in her heart.
I’m clearly several years older than Jiang Yuelan. Why should I have to call her sister?
Yet when she raised her eyes and glanced at the height difference between the two of them, then looked at the composure and mature aura on Jiang Yuelan that did not belong to this age, she suddenly felt that calling her sister did not seem improper.
Moreover, the other party was a suspected witch.
Whatever she said was whatever it was.
How would she dare to refute?
“All right, Sister Xiao Lan.” Su Bai obediently replied.
“Let’s set off.”
Hearing this form of address, Jiang Yuelan nodded in satisfaction and took the lead in walking out of the dormitory door.
Su Bai quickly picked up her bag and hurried after her.

《如何做好一名卧底—速成篇》有云：
“做卧底的第一要义是什么？
信任，信任还是tmd是信任。”
无论是刺探情报、引导对方行为，还是关键时刻撤退跑路，这一系列操作都得建立在信任的基础上。
没有信任，别说完成任务，能不能保住小命都得打个问号。
那么如何才能建立信任？
苏白把书上内容总结了个九字真言：
不惹事，敢担事，会来事。
所谓不惹事就是不给卧底对象找麻烦，这是底线，可以有效降低负面评价。
敢担事就是要给卧底对象抗伤害，有必要时候要毫不犹豫的背黑锅，可以增加正面评价。
至于这会来事，那就是对准喜好猛猛进攻，提高好感度（划掉），信任值。
这是她熬了好几个通宵总结出的“精髓”，越想越觉得有道理。
只不过……这套打法怎么有种说不出来的怪。
怪在哪？
总感觉这套理论放到什么galgame恋爱游戏，去攻略女生也毫无违和感啊。
不对不对，这肯定是错觉，自己只是为了取得信任，这怎么能一样。
苏白在这里有一头没一头的在脑袋里复盘着她的计划。
对了，有主意了☝。
“江同学，我来帮你整理吧。”苏白灵机一动说到。
“感谢你的好意，我过来的挺早的的，现在已经收拾的差不多了啊。”江月阑微微一笑。
然后指了指苏白身后那堆行李说：“比起帮我，你自己的东西还一点没动呢，还是我来帮你吧。”
“我不用了，我自己就可以了。……”
苏白直接拒绝，过去想要自己收拾，但是江月阑却没有停下的意思，毫不在意的旁边打着助手
苏白心里有点发怵——毕竟对方是疑似魔女的存在，她不敢强硬拒绝。
甚至最后眼睁睁江月阑为主力，她则像个没用的小媳妇在旁边，偶尔帮衬两下。
看着江月阑忙里忙外，自己却插不上多少手，苏白的眼角忍不住抽了抽，
久违有了那种“蛋疼”的感觉——虽然现在她已经没有那种东西了（悲）
抛开江月阑魔女身份不谈，江月阑对自己还真挺不错的？
额…
大概、也许、可能这也算是达成了自己的目的？跟江月阑打好关系……
…………
个鬼啊！这简直倒反天罡啊。
苏白在心里哀嚎，她心里肯定觉得自己是那种处处需要别人照顾的麻烦鬼吧。
苏白感受到的那种友善说不定是某种伪装，只是不为了暴露身份才……
她可是魔女，成为学生混在校园里面，肯定有秘密。
谁能知道她的真面目，没准哪天自己就被魔女大人给清算了。
苏白脑子冒出了个画面，暴露真身的江月阑掏出来个笔记细数着上面苏白犯下每一件事情，然后用着残忍手段逐条折磨她。
好，好恐怖QAQ。
至少她认识那几个魔女像是会干出这种事情的人。
决绝不能让这种事情发生！！
“江同学，太感谢你帮我，今晚我请你吃饭吧，吃什么你来定。”
江月阑歪了歪头，然后嘴角微微上轻声说到：“好啊，校外门口有个西餐厅，听说还不错，一起吧。”
肉疼啊。
那个店一看就不是什么便宜店，虽然以自己工资存款不至于消费不起，但是说不心疼是假的。
“可以的，可以的。”苏白表现倒是很大方。
开什么玩笑，就算没有协会报销，这顿饭贷款也得请，不但是回馈才刚帮助，还是个能提高信任值绝佳机会。
那些影视剧里面，饭局都是谈事成事最好场所，说干就干，抓紧机会。
时间一晃就到了晚上饭点，在下午这段时间，两人忙乎完卫生打扫，两个人轮流洗了个澡
然后江月阑似乎是累了，冲了个澡，而后躺到床上，小睡了一会。
而苏白则是等着江月阑快要洗好从卫生间出来的时机，到楼下小卖部采买一些不好携带的生活物品。
并且再回来时候敲门询问是否换好衣服，回避了可能会发生的那种狗血香艳剧情。
只是因为苏白心里清楚，那一天她的三个队友说了很多谎言。
但唯一一处她们说对了，也是骂醒了苏白：
自己不能凭着这副后天得来女性身体就无所顾及、肆无忌惮，接近别的女生。
哪怕对方不在乎，
哪怕对方永远也不会知道她的过去，
哪怕这会给她自己的生活带来苦恼，
但苏白也不能接受的自己的“越界”之举。
就算无法完全避免，至少也得尽量做到问心无愧。
“走吧，江同学，
“哇，晚上你新换的衣服还真挺帅气的，和你特别搭。”
江月阑换了身行头——从下午那身朴素的运动装，换成了一套哑光黑的“斩女风”风衣，
配着紧身牛仔裤，整个人透着一股利落的中性美，比下午多了几分疏离的酷感，这一套穿在江月阑身上特别合适。
夸一句既能拉近距离，又能涨信任值，不夸白不夸。而且说实话，这身风格确实帅气，更加符合自己对于江月阑的第一印象。
“你喜欢就好。”江月阑嘴角弯了弯，率先迈步，“走了，小白同学。”
“小白同学？”这称呼听着又尊敬又带点亲昵，苏白愣了一下。
“咳，这么叫是有点怪。”她清了清嗓子，摆摆手，“要不你以后叫我苏白，或者直接叫小白就行，以前很多人都这么叫我，我不介意的。”
“好呀，小白。”江月阑应得干脆，却话锋一转，“不过作为交换，你也不能再叫我江同学了哦。叫我月阑姐或者小阑姐都可以。”
什么啊？苏白心里嘀咕，自己明明比江月阑大好几岁，凭什么要叫姐姐？
可她抬眼瞅了瞅两人的身高差，再看看江月阑身上那股从容和不属于这个年龄的那股成熟感，忽然觉得叫姐姐好像也没什么不妥。
更何况，对方还是疑似魔女的存在。她说什么就是什么，自己哪敢反驳。
“好的，小阑姐。”苏白顺从地应道，“我们出发吧。”
江月阑听到这声称呼，满意地点了点头，率先走出了宿舍门。苏白赶紧拎上包，快步跟了上去。
