I have some more, where the family discovers, but that wasn't what you asked. But if you are interessted, it would be no problem.

Also not exactly what you are looking for: MC discovers the unrequited love for the same gender of an acquaintance:
koimonogatari
Blue Lust
For your love

Sorry, I just recently started to tag my mangas. In these situations I am always regretting not doing it since the beginning because I can't find everything. But maybe you enjoy some of these:)
