Review Detail of DaoistCGid7j in Hachiman Hikigaya Can Level Up

One of the best stories I've read, but there's one thing I didn't like: the hero isn't well-suited for the role. Why? Because he often feels nervous and afraid, and gets shy quickly, almost like a girl. The main character's personality doesn't develop much; only his strength increases. It would be better if he didn't feel so embarrassed all the time.
