For real! It felt exceptionally bittersweet and for a yaoi with a pretty cute plot oddly very real. I think people see what they're told happened and look no further, like it's very obviously not about cheating?? Very strange behavior but what can I expect from the people who hate when a character even talks to another person romantically, they see red when they get a whiff of a character with a past

He was groomed???? Very obviously a kid as well, middle school aged people are CHILDREN. He didn't help his brothers boyfriend cheat, he was groomed by an older man and was raped/molested and had it happen to him again. You guys really have no empathy or critical thinking skills. The whole part about him "suddenly" not liking it was not just bc he was in love, it was to show he never liked how he was treated and didn't have the words for it Until someone who actually cared about him showed him it wasn't right to be treated that way.
The bad guy is the fucking rapist, you guys just hate victims
