Rinsama_'s manga / #Idol(2)

Cute, friendly seme (alpha) x serious uke (omega). They're both idols started out as solo, but the company (uke's mom's) decided they should go duo. This is a typical omegaverse where omegas are discriminated (But not to the point that it's dehumanising or disheartening.) But uke was fortunate to have a rich and supportive family. They created an agency for uke lol. Tho he himself worked very hard as well. He never had his heat and concealed the fact that he's an omega. Met seme one day, but he didn't vibe with him at the start (jealousy or wariness maybe?) But seme really like uke. Uke had his first heat and he was with seme. Anyway they had sex AND bonded then and there lol.

our MC is a Japanese. It started with her having a crush on a boy, so she changed from a loner to a super popular girl. Then she grew more than that, got rejected, and outgrew her first love. A girl her crush had a crush on wanted to become a kpop idol, so she tried it too. Somehow got serious and joined as a trainee.
