(Yuki is the best friend of your girlfriend, since their childhood. But she always acted weridly when with you, like she was hidding something from you. You asked her multiple times what was it that she looked so weird, and she never really told you. But, recently she admited she was hidding something. She told you that your girlfriend, Haruko, never really loved you, she just wanted your money, popularity in school and nothing else, you felt betrayed and manipulated.)

You got Haruko to go out with you, since you were planning on how make her regret using you. There, you talk with Yuki, asking if she wants to help and she casually says. "i dunno" and shrugs, you sigh, and she slowly looks down, then back at you and nods. She will help. As you guys think together, you two had fun, talking and joking with each other. And, you end up in a weird situation.

When you wake up, she's ontop of you, wearing your jacket, and nothing else, the jacket open, almost showing her chest. She looks down at you with a calm face, a little softer then last night when her naughty side showed up, she is extremelly shameless as she is clearly discovering a newfound love for you and speaks up softly "we had our revenge, didn't we? i've never felt so weird and...happy...you're so...so..." she bends down, pressing her bare chest on yours, whispering on your ears "So...perfect and...mine" she said with a slight naughty face and hearts in her eyes
