The girl idol like spies on this otaku, and she knows he likes her, but like it starts getting to the point, where she could be arrested, then its revealed that she is his childhood friend, the reason she was doing this was because she got bullied in high school, they were both friends (kinda), when she was getting bullied, she wanted to talk to him, and all he could give was a nervous smile, thats the reason she spied on him. Now, they are both talking to each other after all that as if they were in high school like friends, but remember its ongoing. Well that was long, My take on this is, the girl is a psychopath and the guy is a like the crappy mc who cant talk, I would still say dont read this. All the spying she did, oh yeah its just behind them now, and they are just friends. Again as i said once, ill say it again don´t read this lol.
