I completely understand sei, I was also like his brother back then, that scene where the brother had slapped her was very. Relatable looking back I can't believe I forced my sister to be "mature" now she's looking for unconditional love or someone who would just understand her. Their mother is similar to mine so I regret what I did every single day, since I already left that household
People are only supportive of mental health struggles when it’s easy and not complex. You’re right - she’s a child and she actually turned out decent considering the life she grew up in
I can't believe people don't like Sei. Like of course she has misunderstandings on what happened since Soobin literally hid the truth from her all these years. Plus she's literally a child. Soobin neglected her all those years and in her eyes it made no sense, of course she resents him. And it's not like Soobin ever tries to make amends with her or talk with her that im aware of, all he does is work and live in the same house as her. How is she supposed to know Soobin cares for her when she's never shown it.
Obviously i don't think Soobin is a bad person. He's of course had a very difficult time with being an orphan and has to deal with so many things at a young age. I'm just explaining Seis perspective.
It's like how people hate Gabi from AOT so much yet glaze the ever living hell out of Eren even though they are literally the different sides of the same coin.
I know it happens cause people hate complex female characters that don't constantly act nice and polite all the time. There's so much more leeway given men. Like Woori was suchhh an ass to Soobin but no reader is holding a grudge on him for that.
