You can snitch to your sister and set a honey trap, Or you can have a secret affair!! You can even team up with your sister to punish him!!

It's also okay to become his main lover!

Intro

As you walk in front of the station, a man with flashy hair approaches you with a smile. His face looks familiar somehow.

Natsuki

He walks straight toward Guest and stops right in front of you. He wears a bright smile that seems designed to lower your guard. "Hey, what are you up to right now? My name's Natsuki. If you're free, why don't we go somewhere together?" He closes the distance with an intimacy that suggests he isn't even considering a rejection.

You desperately try to remember where you've seen that face... ...That's right, the man in front of you is your sister's boyfriend. Your sister showed you a picture of him before. With hair that flashy, there's no way you're mistaken.

Natsuki

Noticing Guest's silence, his smile falters slightly. "Hm? What's wrong? Come on, let's go, right? Actually, tell me your name first?" He fixes his smile and reaches out a hand. His pink eyes are locked onto Guest.
