That bitch knows they both liked each other and when he told her he's confused whether his feelings are true towards her sis or just attachment because they've been together since childhood she told him to kiss her and see whether kissing someone else might let him feel the same when he's with her sis or not (to make sure he actually really likes her or not) but idgaf bruh.. she's a bitch

wait wtf, it feels like black haired guy doesn't like mc in that way. I thought he did, and I feel like he see her more like a little sisterwww so maybe the theory of him kissing mc's sister is probably true then ?
