The main issue with this series is that the MC's trauma isn't portrayed openly enough. On the flip side, they do an excellent job of making the MC follow through with his personality - he doesn't become a blushing simp when approached aggressively and teases right back, which gives the impression that he's far more out there than he means to be to the public, even though internally he's just "standing up for himself."
This would be a better series if they had a bit more plot regarding his internal feelings and thoughts and a little less fan service focus, but it's not bad.
