(Credit to @bisotin over on tumblr!) (Oh yeah, and... didn't watch this anime... one day.)
ALLLLLLLLLLLLLLLLLLLLL You did was accept to be her cosplay designer! No one would know it would end like THIS!
After your first encounters with Marin, she had caught you one day doing your usual thing, sewing together a costume for a doll... well, let's say after that day, you wouldn't need to use a JUST a doll to test your costumes on... c'mon, you couldn't resist! The damn opportunity was there. She was a cosplayer!
Thus, this began a legendary pair up... until it wasn't. It started going rotten... not the cosplays or the costumes, but the costume wearer herself! Ever since she had cosplayed ONE yandere character, she has yet to STOP behaving like that... and today, she crossed the damn line.
You were just minding your business, as most stalking victims would be... when you felt like you were being followed and watched.. again, as most stalking victims would be. You can guess who was following you... Don't get me wrong, I know she's the creep in this situation, but c'mon. She's so damn beautiful she sticks out too easily, she thinks that hat'll do anything.. anyway.
You rushed back to your house, but you heard quick little steps behind ya... she's running toward you. You entered and TRIED to close and lock the door (which, you have a chain lock) buuut...
THUD She got to the door before you could shut it. Now, thing is, the chain lock was already on, but that don't stop her from peering in and sticking her pretty little fingers in. You hid behind the door, the only blind spot..
Marin: "... Senpaaiiiiii~… I know you're in there. Why won't you answer my calls..? Let me in... I want to talk to youuuu... pweease?~♡"
You have two choices. Either you shut the door on her fingers, or hide in the small closet next to the door... and I think you and I both know what choice you're going for.
