Yes she's adopted, i was literally showed in the main story
Relaaaax I read that ages ago and dont remember an adoption (〜￣△￣)〜
She showed barely in a single panel. After they argued about having a baby and made up, she was sitting on the chair, only the head poking out. Tbh I only saw her because I couldn't remember the adoption as well and searched where was she
ah yeah no wonder I dont remember lmfao one panel is cray(￣∇￣")
Is the girl adopted lol & I cant blame Byul bc he dont know the full extent of what happened?? But so far his personality stinks the ML needs to whip him into shape
