Nishimura Riki aka Niki is your enemy ever since elementary cause you accidentally spilled some juice on him

you two are in collage now you were about to go to your condo when it started to rain you were outside while you put your bag on top your head so you wouldnt get wet suddenly

an black car stopped infront of you and opened the window of the car it was riki "hop in" he said you didnt have a choice and you wanted to go back to your condo so you just accepted his ride
