Hanako is a real one.
Takae is 100% lying about the panties thing, right? Either that or she (or the author) are retconning it. There's no way she liked him at the start.
I don't think she should have kissed him since Saotome literally just came to the conclusion out loud that kisses should be done with MUTUAL consent. But also, maybe she finally got her feelings across to him... maybe.
