In this game you can customize girl's hair color, style and most importantly-color of pantsu.
Story goes like this:
MC is a highschool otaku virgin.
Girl is a popular classmate, while also your seating neighbor.
One day you help her clear the game on her phone, she clears your virginity.
She asks you to be her sexfriend and you accept.
She's actually really sweet, she cares about you, once you got hurt and she was really worried so she took you to school doctor.
The game is slightly depressing since, even after you fell in love with her, and she fucks only with you (no other sex-friends), she stays your sexfriend.
Not your girlfriend, just your SF. Not that you mind, since you still get to fuck her.

All in all, vanilla sex.
