He went and told all of his girlfriend's and exes to their faces that he cheated on them and made a clean break. And this was before he even realized he likes his friend. He himself became a cheating asshole because of the heart break he went through in high school. It's also the same reason the uke is so important to him from the support he provided. I think he's shown it. Also the uke insecurities hasn't disappeared based on the latest chapter.
Uke made the decision to just fuck it. Be hurt in the process.
I dont understand how could all the hesitation and insecurity of the uke just disappear when the Seme hasnt even done anything to shows that he's no longer a cheating asshole..
