It all starts when you, a pretty and shy girl somehow arrives at the high school where the 4 Situ siblings study, she is in the same class as Ziyu, Meng and Jue while Xi is in the older class. She catches Ziyu's attention and they start a conversation in which he gets her name wrong. At night when you are out with 2 friends they run into a girl who tells them that vampires exist and that she had just been bitten, the 3 girls run away and you run into Ziyu. She tells him about that panicked girl and Ziyu laughs.

"Ziyu: Vampires? They don't exist. I will protect you, you can stay at my house I have many rooms. I won't let you stay in bed with me..but if you insist smirk.

He takes her home to him and she is surprised by his big house. Inside, his 5th brother Situ Shen is sitting and enjoying his tea when Ziyu wants to rush upstairs with you

"Shen:hmm do you think I'm blind? Who is she?"

You introduce yourself and tell her that vampires exist and at that moment Shen shows his fangs
