I don't get why u are saying he was using itsuki. so by your logic everyone that tries to date other ppl and move on from their unrequited love are using them? lol
He hadn’t come to terms with actually getting over his desire towards his brother until Itsuki made an ultimatum. I’m not even interpreting this was just one chapter ago, that’s literally the plot. It’s even acknowledged as such he’s entirely in the wrong. It’s only rational to be offended to be chosen as someone’s backup, more so when despite all reasons that an incestuous relationship would never flourish, he still held out hope for his brother being a romantic option. Even if we took out the element of incest, if you’re unknowingly someone’s rebound that affects a relationship, as your partner isn’t fully invested in the relationship. He made a hasty decision because he felt cornered by Itsuki possibly ending the relationship. Itsuki deserves better or least the time to actually have Airi take the steps to regain Itsuki’s trust. This is a fictional plot that reduced an otherwise serious relationship hurdle to just taking the time to get a haircut to make amends. In real life Itsuki should have even walked away entirely from the relationship until Airi actually was over his brother naturally not his anxiety, loneliness, self hatred be the catalyst to reestablishing their relationship. Nothing about this is healthy.
I'm not saying it's healthy but I simply disagree with saying Airi was using Itsuki. I went through the story again and nowhere it was said that he was using him as a rebound etc. What I got from this story is that Airi knew his feelings or more like this weird attachment turned confusion was wrong and he wanted to move on. He met Itsuki who he thought he could love and truly fell in love with him and that's what happened. You can't say "be chosen as someone's backup" when the character says "i wanna move forward and take a next step". You are forcing this whole "he was a replacement" when at least imo that's not what it was at all. But I suppose we can agree to disagree
God that was rushed. Not even a single day that HUGE secret was revealed. Itsuki gets a haircut and all his concerns,doubts, anger is magicked away. Your boyfriend just told you he’s been in love with his brother long before and during your relationship that he’s been USING you as an emotional crutch, but somehow the severity of this is overcome in just a day? Enough to sleep with him upon his declaration of “love”? Man if the art wasn’t so god damn pretty I’d have rid myself of such nonsense. The plot was so serious and filled with angst and it’s been just reduced to a haircut. Sigh.
