Read the afterword, author wanted to show that after getting hurt, Yaku wasn't able to recover, and Hino was successful in healing him.. But author couldn't potray that very well.. no character growth for Yaku.... may be he started feeling for Hino but suddenly just saying "I love you" doesn't adds upto apology and character development..

Now I want to see their kids man!!!!

https://www.mangago.zone/read-manga/ibitsuna_bokura_no_katachi/ are you talking about this one?? Your description matches with this plot..but its not from the same author
The translation was bit off..
Its good if I exclude Ouu(the big brother) and Kai's physical harassment on yuito
That's what I'm sayiiiing... The main couple is so cute and the seme is literally a walking green flag. All that shit with the other brothers ruined it for me
