Umeshu

So the seme like owns a watch company or something and the uke wants nothing to do with him at first (and I think uke is crushing on his bro?) but like gradually it happens also there is an age gap because I'm fairly certain he was a student, possibly uni?Sorry its minimalistic it just popped in my head and I can't remember much about it but now I just really need to know what it is! Please help end my fujoshi suffering! T.T
