I remember that it was a student council meeting or something they were students and one girl was being really mean to this guy and he was handing everyone coffee or something but he was pissed at the girl so he put semen in her cup and they thought it was like concentrated milk and since they were in the middle of the meeting and there were people around she had to drink it. Later she started liking it and at the end of the chapter he gives her another cup of coffee with his stuff in it and this other member was all like how come shes the only one who gets coffee with concentrated milk in it. That's all I remember can anyone help me find the title.
