Me running from my obligations be like
Slightly older UK, Aomine, Haizaki, Nijimura, Kise, Murasakibara having to meet s/o's younger brother and not being very excited because who wants an annoying kid anyways. But when they meet him they find out he's a teenager and immediately falls in love with them and counts them as brothers. How would they react to that. Like how would they be around him and such.
