I think, he felt betrayed and most of all he’s jealous of our seme’s happy family. Our uke doesn’t have that so he hit where it hurts the most; his weakness. Even out of manga that is the most defense or offense most of us do when we try to get back at a person. I’m not saying that is good but that is sad reality.
Whatever his reason is it’s unfair that he robbed Yiyi of raising his own child and let alone raised and loved the child for 3 years without knowing it’s not his.No amount of money can settle! Not unless our seme does the same thing as Yiyi.
based on the dna result Rourou is seme’s child.
