Tbh I don't think that he was happy that he was targeted by accident. When he noticed that his suit wasn't fully charged he was scared for his life, if the blonde dude hadn't been with him he most likely would've died. And then he finds out that someone messed with his stuff, put his life on the line, wasn't even that sorry about it and thought about it as a joke. On top of that, all the red hair dude has to do is write a letter of reflection. MC must be pissed af. But if he wants to get into the university he needs to have a perfect record, so getting mad about something like this might work against him, which is why he smiles and says that it's okay (or whatever his exact words were) blonde dude picked up on his emotions, and I'm pretty sure that they were similar or exactly the same feelings that MC had when he was in the basement and destroyed stuff. That's why I think that blonde dude is pissed and MC too for that matter. Of course that's all just the impression I got from reading, so I could be wrong lol.
why is he pissed? o.o
