Ore no Tsugai ha Thoroughbread Omega
Two second generational actors have to act against each other in a drama, and the alpha guy thinks that the actor he's playing against is an alpha but learns soon enough that he is actually an omega.
Miss You, Lucifer
This story is about how a famous celebrity is a fan of an unknown celebrity. One day he overhears the unknown celebrity saying that he'd like to fuck him, so they start having that type of relationship. I have to say, that I really liked it however it was really short, would be much better if it was a bit longer :)
Exotic Love
A story about how a chaebol fist falls in love with an actor he sees on screen, he gets an "uncomfortable" feeling on his heart, and he thinks that the only way to get rid of that feeling is to get rid of the actor. In one party/orgy, he gets rid of the actor by planting drugs in his appartment, however in that party the chaebol gets overdosed and forgets what happens. 5 years later, he meets with the actor again at a bar, now the actor has turned into an director, and needs a sponsor for his movie. But the director asks to talk to him privately as he wants to apologize for smth that happened 5 years ago. They meet up privately and the director tells him that he was the one who gave him the ecstasy pills that made him overdose and then topped him... The chaebol who has never been topped and only been a seme, who was never able to cum, slaps him on the face and then orders him to suck him off. The director sucks him off and stimulates prostate until he comes, the chaebol runs away, and after that starts getting addicted to him... I love it! This manga story was hella good, like the relationship between them was hella good, the angst was just OH MY GOD. Everything is good, I hope I get to read the novel that this webtoon is based on :)
From Points of Three
An actor hires a filmer, to film sex scenes of him and his sex partner. This is all so that the seme/actor can manipulate the filmer into becoming his boyfriend. The sex partner also becomes interested in the filmer, however he doesn't have any chance of getting together with him and instead becomes his friend. The sidestory is about the sex partner who starts dating a hoobae that has a crush on him, I liked this story much more than the main story.
Nanase the Idol’s Ω Secret
An omega wants to become an idol, in a world where only alphas are able to become idols, meaning he hides his second gender from people. He gets to debut but only with an alpha, the alpha feels that he is his fated mate and also finds out that he is an omega. He treats him nicely and eventually bond. It's a-ok, not to reread again, nor to be recommended to others.
