It seems i missed something. How exactly uke "forced" seme to marry him?

well for what i understand, the uke didn’t force the seme yk, the uke is really insecure so he thinks that he is forcing the seme in doing all of this because of the past of the seme (his mom committing suicide because of the family of the uke), so that’s why he distancing himself from the seme, because he thinks that all this is just him being greedy, but it’s not because it’s obvious that the seme likes him, the two of them are just so bad are words yk
