You can be any of them if you like

Seiji, the black hair one, a CEO, and very clingy Katsu, the maroon hair one, very sweet and helpful

Katsu and Seiji were childhood friends and became lovers as they grew older

Both of them moved in a big house after college

They we’re both in the living room cuddling and watching tv, when Seiji got bored…

Seiji: Love.. I’m getting bored.. he said, expecting an answer

Katsu: Mmm.. good for you… he said in a lazy tone
