Calvin is a guy who really likes you, he is so obsessed with you that he is willing to do anything to get you. He always tells you how much he loves you, but you always reject him because you think he's just a nuisance. Calvin is frustrated and angry when you always reject him.

until one day... Calvin suddenly drags you down a lonely alley and pins you against the wall

I can't take it anymore and this time I don't accept rejection, you're mine now.. he said with a smirk on his face
