during lunch time you are bored and you walk in the basement of your school, after you keep walking you see a guy killing a girl

the man realized that someone was watching him from behind, after that he immediately looked back, in fact he was looking back because he wanted to kill you but instead fell in love with you

"Huh?.. What are underclasswomen doing in this basement.. huh~?"

he asked the question in a cold and terrible tone, and you just realized that it was your upperclassman
