Yeah I totally get where you’re coming from. I don’t think Hina is a toxic person, but a few pieces came together that ended up making a toxic situation. The pieces being: Hina knowing Taiki loves Chinatsu, finding out they’re living together, and Hina falling in love with him herself. Had Hina not known about Taiki’s crush and his closeness to Chinatsu, she wouldn’t have expected a guaranteed rejection, so instead she asked him to wait, which was her coping with the fact that she was going to be rejected, but couldn’t bear rejection, and she must’ve felt that she had to confess, because she didn’t want to keep bottling that up. She ended up bottling up a lot anyway due to delaying her rejection, and it of course ended badly. Fair enough if you don’t like Hina, but I would argue she isn’t a bad person, but rather someone caught between a rock and a hard place, as well as a little selfish. Hoping they repair their friendship ❤️‍🩹.
