I read the first 20 chapters but didn't connect with the novel.
It's hard to explain why, but it's mainly because when reading it, I feel like the MC is simply flying over the story: when he does some actions, the direct consequences of it are vaguely explained, but the actions themselves do not seem to be connected with each other nor to a greater plot.
When reading it, you feel like the MC does some things in a specific location, goes to another place, does some other things, and the cycle repeats, without an end goal.
That and some parts of the writing I find lazy. While this is a harem novel, the female characters are empty shells to further the MC's needs at the moment, however, they feel as disconnected from things as the MC, so you tend to get bored very fast.
