I know, right? Totally agree. I don't like Ichimaru one bit. His unrequited love would have been sad if he wasn't such a dick. And after being awful and forcing a kiss on haruto everyone is quick to comfort him and shift the blame to poor haruto. "oh, haruto must have said something to make you mad, it's ok". What the hell? Haruto has 0 blame in that situation. Honestly, izumi's punch was so satisfying, he deserved it. He deserved an apology after saying such shitty things about haruto and his happy relationship just because haruto didn't magically notice his feelings before? I don't think so, buddy.

So I get why it just wanted to quickly wrap up the whole mess with Ichimaru without being too serious but I didn't like it.
Haruto shouldn't be made to take part of the blame because he didn't understand or notice Ichimaru's feelings for him. Especially when Ichimaru wasn't really completely upfront with his feelings until after he confirmed that Haruto was in a happy, fulfilling, committed relationship. I can look pass him being pissing in high school because he might not have known how to handle being gay and being rejected in one swoop. As an adult though? Naw. He didn't deserve an apology and his own apology was sh*t.
