not 100% an office romance but its around that
i cant remember the title, if you can help me that would be great
this all I can recall about the manga, so an older female(i think) and younger male I believe and he can read minds.
he comes from a rich family so the mom does not like that he is dating the girl
the guy has siblings and they all have beautiful appearances and can read minds (black hair blue eyes maybe?)
the girl has funny and crazy fantasies like daydreaming and stuff.

if you can find what I am talking about then thank you very much.
