Didn't like the seme's friend made the uke feel like shit
Didn't necessarily make him feel like shit. He just warned him (with the truth). It was for his friend's sake and anyone else involved since the seme gets dangerous when his emotions run high. The uke was included in that warning for safety reasons.
It was never said, but I get the feeling the friend been around long enough to see him take care of others behind the scenes for the uke as it was briefly implied.
As an art graduate this shit is the worst thing that you can do to a another art student or artist. This shit is not okay. Plagiarism, stealing then she makes him feel all shit about it too for asking. Like no. Don't care is she cried and felt bad. You can't give back any recognition you got for it back to him. She's known as this well known artist using his work. No way. And she gets to be married. No way.










Usually I'm like stay away from my couple but in this manga I know I'm gonna laugh so I can't wait to see what she's gonna do lol
