I fully agree on everything. Except for the part that the seme didn't ask for permission about the marking. Correct me if I'm wrong, but as far as I can remember, he didn't know that uke is an omega. They must've marked each other unintentionally. Coz when seme got sick and everything, they were looking for the "omega" who marked him, and he was still in denial that it was uke coz he still believed he's a beta until the later chapters. Also explaining why he jumped to the conclusion that uke was the one who impregnated someone rather than him impregnated uke. Because to him, uke getting pregnant was impossible coz betas don't get pregnant.
I think this explains but DOES NOT excuse why he was an asshole to uke before.
Okay, at this point i still feel mad at the seme, though a bit sorry too. He was shitty and really self-centered when he was young, no argument there. Even though he did suffer it was all on him. He didn't even ask the uke's permission about the marking. Then, he didn't even confront or hear out the uke when the uke got pregnant. He is making up for it now which is good but all the uke wanted was some peace with his daughter. And the seme and his sister just came and crushed everything. He's cornered and all he could do is go along with what seme wanted to help his sister. They're borderline threatening him with lawsuit (idk bout you but it seemed like that to me).
I just really feel bad for the uke. He has nothing but he still pushed through to raise his daughter and set up a business. He didn't need the seme. He could live peacefully if he wanted.
Don't get me wrong, their daughter have all the right to get to know her biological parents and she deserves all the love in the world. What I am saying is that uke's anger amd hurt are reasonable and that if not for the seme coming back into his life, he could've lived peacefully with his daughter. Uke also understands what he can and cannot give her, like grandparents or relatives, luxury school and stuff etc that's why even though it hurts him, he's got to endure it for his daughter.
There's another issue of that jerk guy (neck tattoo dude) but that's another discussion for another day.
p.s. please dont lash out at me. I am a very soft person. This is just my view at the moment and this might change as the story progresses or when and if I re-read from the beginning.
