I genuinely like dahae's older sister ok, especially since she really helped her family by being the sole bread winner. But I can't imagine a normal human being who would kiss the person their younger sibling likes and would live another day not feeling a bit of guilt, and that's a huge yucky red flag for me ngl. And fuck the men in this story bruh, the only normal option here is the brown haired guy
I bet there's gonna be a scene where kiheon pulls out the "I got along with her because of you" card to gaon, then MC will hear/see it, then snap out of her feelings...damn, im at the point where I'm making up my own plot WHY IS THIS TAKING SO LOOONG
