A number of reviews have already covered the problems. 1. Annoying harem trope: every woman who meets the MC wants him. 2. The sidekick who exists just to be abused by everyone else. 3. The sound effects and accents were overdone. 4. The ending left much to be desired.
This book was okay, but I’ve read the reviews for the next two books. I’m out. The harem was barely tolerable in this book just gets worse.
