Seme is still undecisive up to this point. He’s like postponing the child thing since he knows uke will die if he gives birth. He even asked the dr to make a suppresant. But he still keeps mentioning that the company would be his (which is only possible if he will have a child with the omega). I’ll suggest reading after more chapters. Right now, everything is still vague really.
About the love, its the common trope on omegaverse. Omega falls in love with an alpha who they think treats them right. Plus a hint of stockholm syndrome i guess?

Actually, he is not indecisive at all anymore regarding that, though?
I 100% agree that this started out really awful - if I hadn't only found and read the entire story now (and actually, on top of that, started by reading some of the last chapters where he's already head over heels for him instead of the first ones), I would have absolutely dropped it after the first few chapters just like LOFFE said.
By now, it's a bit different (though IRL I suppose what he did previously would still remain unforgivable no matter what - these classic 'redemption arcs' can only happen in fictional stories like this ╮( ̄▽ ̄)╭), because since ch.30 or so, he is openly in love with Rain and has made that unambiguously clear. I absolutely didn't get the impression at any point that he was *postponing* the child issue after that. Rather, I believe he's pretty determined to not go through with it at all and just worried about how he can make it so that Rain would ideally never have to find out about the enitre thing. It's a precarious situation, because after those initial shots, they're now in a situation where Rain would probably have to keep receiving those suppressants for the rest of his life so that things remain the same and there isn't the chance of that pregnancy happening by accident (and for all we know even then it may not be 100% safe).
As for the company part, the way I understood it was that he felt his chances were currently good even without actually having said heir, because of his position as the favored candidate and no other candidate being actually able to achieve fulfilling that condition about the alpha heir either anyway..

Oh, and regarding the original question about why Rain would fall in love with him...
The way it came across to me was basically - there's suddenly this super insistent, good-looking, unspeakably wealthy guy, who's claiming to love him, showering him with riches and saying he'll do everything to help him achieve his dream (including making a huge private studio for him at his luxurious mansion and arranging for all sorts of famous celebrity-level people from the field to come tutor him, etc.), so... you know ╮( ̄▽ ̄)╭
Let's not forget that, until now, Rain never actually knew about the real background of what they actually wanted him for. He's already begun to suspect and figured out parts of it (like the fact that he's an omega), and for now, he's decided to try and ignore it himself and act like it doesn't exist, because he's feeling happy with the way things are now, but he still hasn't found out about the whole truth yet.

Sorry, I got spoiled so i kinda know what will happen and thats why I said that seme is an undecisive guy. While I do agree with what you said, mostly, i still believe that this is one angsty omegaverse story where no matter how much effort the seme put in order to protect his omega, external factors are always there to challenge his goals yknow. Add it to the brother who is also eyeing the position in the company and is on the lookout for an omega who’ll bear his child. Even without having spoilers, I would still belive that seme is undecisive. I can’t explain it properly. But if I am the alpha, knowing he is a precious omega that is targeted by a lot if people, how could I not mark him as mine and what is that one thing that could mark ur omega as yours aside from biting (if it works here, each onegaverse has their own rules) than having a baby to let others fuck off.

Could you possibly elaborate about the indecisive part, please? Is it something you know for certain (by reading it or being told by someone who did) or did you infer this from the raws by looking at the panels only (without reading)?
(I'm fine with any sort of spoilers, by the way.)
(possible spoiler ahead:)

I did gather that Rain is actually pregnant in the future chapters by now, but I figured it may not have been a planned thing / generally don't know how that came about?
I dropped after 9 chapters because I was so mad how much the alpha is a scumbag and surprised by how much everyone in there could be alright with kidnapping, forcing medication into someone, and all.....
I'm crazyily mad.
Can someone tell me how they ended up together and why he fell in love with someone who was so bad and didn't care if he died to give birth to a child ??
