https://www.mangago.me/read-manga/hanaya_no_nikai_de/ this is just one of the sequel of one of the brothers, is it correct?
It’s not this one. Thanks for trying tho
All i could think of something similar was Yuzuki Family's Four Sons but its not BL. Very wholesome tho i cried
I like that one too! It’s a similar concept but there are diff love stories for the diff brothers that are the oldest
not sure if this is right but its worth commenting just incase https://www.mangago.me/read-manga/sweet_pain/
Japanese yaoi
It’s about a family of brothers (NOT incest).
They have no parents and the older brothers take care of the younger brothers. The older brother is a businessman or something. It’s multiple stories because it’s multiple love stories of the different brothers. Including the working adults + the ones. V wholesome
