They were always just fighting, but then something happened between those friends.
Doha is an alpha, and Jio is an omega, yet they've been childhood friends from early days until now. One day, Doha's heat hits, and right then, Jio—who happened to stop by Doha's place—runs into him...

Doha, whose memories of that night are foggy due to the heat,
sees Jio dry-heaving and thinks to himself: It seems like I must've jumped him, and judging by the lack of any condom traces, probably...

"So... I... I'll take responsibility...!!"

Please, just talk it out, you two... no, let's live together, baby!
