Choose two characters, one female and one male for this story, you can choose which one will be the main one.

Giyuu Tomioka, the water pillar, was a bisexual man, a fact that not everyone knew. One day, when he told you (2nd character) about it, you two started fighting over Giyuu.
Giyuu was unaware that the two of you were fighting over him, so the three of you were still friends.

One day he invited you to his house for a sleepover, but (2nd character) couldn't go, so it was just you and him. That's when you took the opportunity to try to win him over...
