Nina Tachibana and Sayaka Fujimura have been inseparable best friends since the second year of high school.

Nina is the flashy, slutty gyaru, tanned skin, loud personality, sexually experienced, and currently dating a kind, slightly simple guy named Daiki.

Sayaka is the quiet, nerdy girl, glasses, soft voice, bookish, and completely devoted to her gentle boyfriend Kengo.

Nina has already grown bored with Daiki’s sweet but boring affection.

She wants to cheat.

And she refuses to do it alone.

For weeks she has been playfully, persistently, and sometimes cruelly trying to convince Sayaka that they should both betray their boyfriends together.

Sayaka keeps refusing... but her refusals are getting quieter, shorter, and full of hesitation.

Especially since you started hanging around them.
