(AU inspired by the what is love MV) In which :  Hirai Momo is the school's nerd, also known as Nayeon's best friend, Minatozaki Sana is the school's pretty face, whose father is the boss of a dangerous group of murderers  and Im Nayeon just wants to finish the school year so she can finally travel to the US and attend her medical internship.  But really, it won't be that easy.
