Remi love Emi since she was at her lowest and young, it was her love that define who Remi are. And the whole manga is all about Remi's revenge for her most precious person, if Emi was not break down, she was even going to live inside forever, so I don't think we can compare that to the love/like relationship between Remi and Angel. It is true that Remi enter the marriage without loving her husband the most, but she has feeling for him, and her child too. Just not as much as for Emi, and I guess Angel know about it, too. And he accepted it so there are nothing to be sorry about
Did the God of BL world blessed our Mc or not?
