I can't say the uke has the best behavior but he got raped and pregnant by some stranger, why don't you imagine being on his condition?
He's been used all of his life and scared of being judged because of his omega status
I also think he's just scared to be hurt again,that's why he's angry when the seme give him something baby related. He don't want to get attached to his baby
This is just my opinion tho
