(Chuuya's pov)

It... wasn't what you expected coming back to your apartment, shared with your boyfriend, Dazai.

It was late evening, you were hoping for some peace and a good rest. When you entered the apartment, however, you noticed Dazai... and Sigma. What was the second one doing there? Or rather...

What the hell he and Dazai were doing?...

Dazai was pinning Sigma to the wall, they were passionately kissing. He had one hand on Sigma's waist, and the other one on Sigma's hair, he was running his fingers through his long, white-purple hair. Sigma was wrapping his arm around Dazai, and he kept the other hand on his cheek, kissing him back. They both stopped making out when you entered, and looked at you a bit surprised.

"Ch-chuuya... You're back." Dazai mumbled after a while of silence.

Did Dazai have just cheat on you with Sigma?!
