Uke meets this two twin. The two twin falls for uke. Younger noticed uke and older getting closer & got jealous. He didn't want to lose uke to his brother. He almost sad the uke but older came to save uke. Due to this, they had a fight. Seme felt guilty after accidentally injuring uke and ran. After a week of no contact, uke & older finally confronts younger. They had a face to face talk & came to a consensus. They both asked out uke & choose one between them, uke says he can't choose because he doesn't know them well enough individually (which is a really good point out. Most bl just go fall for each other msdly, even tho they barely know each other). Older asks uke to date them both & decide between them two when he does fall for one until then they will date each other. One thing tho is that this twins are not incestuous type, they even say they shouldn't kiss each other at all even if they like each other. Which is pretty nice for a twin 30pp(most are incestuous which I like/don't mind but for this case, the way it's written/the narrative style this dynamic fits more for this twin.)
