Looking for this story (bad explanation warning)

1. It's an omegaverse manwha(?). Mc realized that he's pregnant but doesn't know who the father but he does have the suspect which is his ex classmates. I think there's like 3-4 guy? They are all alpha. All mc can remember that he is suddenly in heat and black out. The alpha that i can remember is
- black hair, the cold types and most potential father suspect. I remember he does wrote mc his number(?) But founded by green hair guy instead
- green hair, he's a chef i think and he is the one try hard the most as a potential father by giving mc a warm oufit, healthy food, etc but the problem is that, when they try to fuck, his dick is too big
- influencer/actor(?) Guy, light hair and he's a twink(?). i think him and green hair does fuck before idk

Oh ya, mc have a girl friends btw whose he vent to about this on first chapter

2. Yaoi manwha, mc have black hair and buff, he's a spy(?) I think. Playful and dominant like. The seme have white hair, wild personality. All i can remember is that mc wear a purple outfit and also high heels

3. Yaoi manwha, this one is futuristic world setting. Mc is reckless wild type and he have a friend who is a robot. Seme have white hair and a wanted person whose mc try to catch but all of them end up with sex scenes. One of the scenes is where he try to use slime cube to catch seme but end up with him stuck (on the wall kind of scene)
