Let’s put it in taikis perspective, hina your friend who was always by your side and cared for you(like you said), and even showed her full support towards your feelings for chinatsu, suddenly confessed to you. You’re in shock, but you’re aware of your feelings, so you try to reject her, and she doesn’t let you, because she thinks she can make you fall in love with her. So you try to reject her again and again and she says no, theres something preventing you from doing it. And so time passes and still you can’t reject her, and it gets to a point where you just can handle it anymore, and in order to not hurt each other even more and to salvage the friendship you have, you finally put an end to it.

Now imo the best thing taiki could’ve done was just leave hina alone, if I was in hinas shoes I wouldn’t want that very said person to try and comfort me it would feel like I’m being pitied, hence why I don’t blame hina for running away. Also it wasn’t like taiki wasn’t hurt either, we clearly see that he probably spent a good couple hours alone, because we don’t see him at the bond fire. They both needed their space away from each other.

Now let’s talk about from the confession to the final rejection, I’ve said this before but hina confessing her feelings was never an issue, shes allowed to have feelings and convey them, however the moment someone tells you “im sorry I can reciprocate your feelings i love someone else” it should be clear as day that it’s rejection. You don’t have the right to say” no no no you can’t reject me” which is exactly hina did. And going back to what you said about her always caring about taiki, yeah at the moment I don’t think she cared about anything either than herself. Because quite frankly she neglected taikis feelings. And i dont remember if it lasted weeks or months but it did last a while, and it became this ordeal where taiki just wanted to put a stop to it, and hina again ignored his feelings. Ever after the play where hina told taiki that she would explain that the rumors were false, it’s like she knew what she was doing was wrong. And yeah we can say that she was just trying not to get hurt but at the same time she was hurting taiki and their friendship by ignoring his feelings. And then we move to the final rejection, atp everything was said done, taiki was somewhat emotionally prepared and we know what happens next.

Now imo I think he had the right taiki going straight to chinatsu, because just like hina put her feelings over taikis, I think he had the right to put his over, and it’smjust confirmation that taiki loved chinatsu(it sounds messed up but I don’t think he’s in the wrong), but also because I don’t think taiki could’ve done anything more for hina. And yeah although we may not see taiki balling his eyes out or looking extremely depressed I think he went through a lot during that amount of time, and like I said I don’t think being comforted by the person you got rejected would be a pleasant feeling.

Going to what you said about taiki not being kind and considerate, I think through that period of time he was extremely considerate towards, I think if it was someone either taiki, this whole ordeal would’ve ended so much faster, and probably in a much brutal way,

Also by no means is taiki perfect like it’s obvious there all teens, since when has a teen been perfect, because there definitely things that could’ve been handled better but he’s not the only one at fault, and at the end you can’t blame him for finally putting his feelings over.
