She's not I think it's waiting for a big reveal of her like talents and strength since she's considered as the strongest among her sibling additionally being secretly trained by the Janitor.
It will be awesome is she stronger than her brothers but in the Shonen manga the best I can hope for is her being equally as strong as a Brothers ╮(￣▽￣)╭
Please, I mean like she is in fact stronger like already stronger than her brothers. Literally she's considered as a final boss among the siblings by her fathers, her uncle, the maid and the janitor however not by the school yet since she's laying low but I really can't wait to see her fight.
Yeah but i remember one of the teachers saying that she's only at her Peak right now and that the brothers will grow stronger than her or something like that, I was like complete bullshit I would hate if they did that but yeah we just have to see what happens next ╮(￣▽￣)╭
I really need to see seohyun kick some ass I feel like they're trying to make her seem weak I don't want this to be another SAKURA she should train under that swords woman lady flying dragon and pick up some sword skills and she can be the badass in that field and I see no eligible candidates for her love interest already see two of them and I don't like them lol ╮(￣▽￣)╭
