I'm not annoyed that they almost kiss but not happening.
I'm type of person... who kinda love natural approach like this, or to be exact in this entire series. Well it's like, both of them is close, they give affection each other, so close that it's like a lover but it's not; they not even refused, or maybe hide it to friends, families, and others; they maybe feels "oh maybe we're mutual" but afraid to confess bcs what if they get rejected and this relationship will changes. So they basically already love each other, but they didn't level up their relationship status, just "maybe it's fine like this".
I.. like this kind of act, like it's exciting, bit a secret but not entirely a secret, it's just something that only happening bcs it's you and her/him. Sorry I just random write this, don't worry if nobody understand it haha
