I really enjoyed this book. I liked the twists and turns the plot took. I like how the MC had to keep dealing with events made to ruin him, often by the seat of his pants. I was being oblivious and missed who the third LI was, which I should have seen coming, but the first book came out long enough ago that I forgot.
While the MC is quite OP, so are many of his opponents. And the hilarity of him dealing with his sister and some others makes him feel more grounded than most OP MCs.
