What I am seeing here is that the uke wants to be treated as a woman (and the little flashback with his mom proved it ) Because think about it why can't he simply be the one buying the flowers or present for the seme and then tells him that he'd like a present/flowers too .

So just be a fucking man and tell him what do you from him and from this relationship
I hate losers like him who can't ask directly what they want and waste time
