looking for a manga for a friend

this is the description they sent me:

It’s about 5 brothers (not incest) the youngest one falls in love with a guy, they are still in school. The older brother doesn’t accept it so he struggles a bit. The older brother then gets into an accident but only breaks his leg. The older brother then finds out his coworker likes him and they start dating after a while. Then the youngest brother gets accepted. There is also a sunflower scene with the younger brother. And the older brother actually has a kid with somebody (might be a maffia girl)
