Find a Yaoi Manhwa

Hi I recently read a manhwa where the MC is red head and he entered a yaoi book. He was supposed to be the bad third character to make the supposed uke life hard but things starts to change.

He cooks their food and he is in a good relationship with black haird guy who is supposed to be uke for another black haired guy.

Black haired guy has 2 baby brothers that MC takes care of.

I forgot the title of this manhwa.

Please help find it. Thank you!
