Yea but tbf her parents were too busy to be in the picture so that's probably why she didn't think of them. She did tell her parental figure sister, after all.Tf? She should still tell her parents she has a boyfriend, whether they give "permission" or not
Not like Yukiko is visually impaired and prone to way more difficulties in life and possibly way more life threatening situations in otherwise normal situations while growing up.I mean I can understand big sis not fully believing her mum, subconsciously whether they knew or not the parents did kind placed too much of a burden on her and had all their focus on Yukiko.
