brother?????!!!!

Hello, I'm the translator. I'm not entirely sure what you mean, these two characters aren't biological brothers. It's only said that they grew up like brothers. Asahi was abandoned in front of the Irino estate, and they took him in. This is mentioned on the very first page of the manga and is also stated in the blurb.

ohhhh thank u I understand also great translating

Ofc and thank youu
