I would like to ask you guys for help about a certain bl manga I've read

The story goes has a thing about time travel in a certain house and some met and fall in love with a person from the past and so they had separated... But they met again although the person he fall in love with(seme I think) is already the grandfather(or was it father) already

Does this ring a bell?

it sounds like ≠ - Not Equal

Maybe Kimi o Watareba?
