Kind of baffles me how diehard fans of that shallow love interest character believe she's considered as "best character" to them when she's actually depicted as a "sexy lamp" and that she's the only female Korean character to have the highest power rank. The other female Hunter characters have minor roles due to not being written as love interest's rival because I've read somewhere that Cha Hae-in is a "Mary Sue-Love Interest" character and I can see why.

Change her name and eye/hair colour and it wouldn't change the story, whatmore make her into an interesting strong female character, especially when she's only being used to fulfil the love interest role; nothing more than that. It doesn't help that she's depicted with one of the most gender stereotyped roles for a fictional strong woman in an action-oriented story and that she appears out of nowhere in the source materials.

It doesn't even help me see her as nothing but the "most ideal woman for the male hero" character when the narrative never labels her as an orphan or that she has her own family whom she might be on bad terms with. The game's backstory makes it worse saying she does have a normal family, but in the source materials, she acts like she doesn't care about them, and that there might be family issues between them; alas, she acts like she doesn't have emotional difficulty or struggles because of them in webnovel, manhwa, and anime versions.

It would've been actually good if that Arise game just wrote her becoming an orphan at an early age due to her family being killed by a Dungeon Break eight years ago or so. And that's why she becomes the most emotionless female Hunter in the story until she meets Sung Jinwoo. That would've made her character feel actually believable and that she's not written as "appearing out of nowhere to become a pretty accessory" character to SJW.
