They don't talk about it but. When the mother appears is the same hair, and when the mc pick up the phone and the ml mother is asking for forgiveness the mc says "I recognize this voice...." and the mother says something like "I had to take this kid (mc) who isn't my own, even when my kid-" or something like that I just remember that it looked like she had a child, that's not mc and that she had to take mc as her child instead of her own child. Maybe I'm tripping?

What if there was another ending where hyunwoo and suhyeok fall inlove and juho gets away from them and opens a bakery of his own and lives his life to the fullest instead of dealing with these bitches
