There was this manga with a very similar plot...... meaning the father in law and husband hooking up. I've been searching for it but to no avail...... please someone link it in the reply if you know.....

Is this what you're looking for? https://www.mangago.zone/read-manga/ani_no_senaka/

Someone please tell me where the scene where one of them goes overseas and forgets the lip balm. I've been wanting to reread it.

It’s from Haru O Daite Ita Alive (sequel) ch. 16 !

Can someone clarify if it's yaoi or bara..... And why is it so...

It's yaoi I think. Cause bara is like.. catered to men but yaois more meant for women? (in not saying that women can't like bara or men can't like yaoi tho)
But this just has more of a yaoi vibe to me. Maybe you'd think it was bara bcs they're pretty muscular but I don't think this is bara.. right? Idk it just has more of a yaoi vibe to me. Baras a bit different. Correct me if I'm wrong tho, just my opinion. ヾ(❀╹◡╹)ノ~
The Takano-san in the end got me
