Moshi Hikkomijian na Joshi●sei ga Stalker ni "XX" Saretara

It was morning. They stood on the platform, waiting for the train.
Yuta Kusakabe (protagonist) peered at Manami Kosaka (schoolgirl) as always.
Every morning he watched her. Every day he yearned for her.
Today he finally decided to make her his lover.
It would be Yuta's dream fulfilled... and Manami's nightmare...

An adventure game stalking the super-shy girl.
Manami seems to attract molesters. Is it her pheremones?
Forced to cum in public exposure by a stalker's advances,
her inner masochist awakens! How will it end!?
