Too many plot holes and continuity errors. The author notes actually say things like "There are plot holes in this chapter, ignore them and just enjoy" and "I don't care about how this is supposed to happen, meh the important thing is protagonist can get more girls now". Also, there is blatant bias against Sakura in at least upto the chapters I have read, so skip this if you like Sakura.

I usually don't review novels that I don't like and just ignore them, but since the synopsis is literally asking for 1 star reviews, here it is.

This really depends on whether it suits your tastes or not. The protagonist has a kind of personality that would appeal to some people and repel some others. Also, there is too much System content. By that I mean the protagonist frequently calls the System to show his stats, etc, even when nothing has changed at all, which takes up a lot of space doing nothing to progress the story.

The character development of the first few chapters have too many logical errors. Author warns that protagonist is going to be naive initially, but she is so naive that she can be considered almost retarded.
