Thanks guys
might sound a bit weird but give me something like this
the uke is older than the seme, and when they were young (that when the seme is a kid and the uke is a teen) the seme wanted to be with the uke, but the uke said no or when he is older. fast forward a few years the seme is taller than the uke and yea he is trying to get the uke's attention
