Hmm. Rough. World building needs help, character building as well. A bit forced overall.Editing good, but needs more captivation to appeal to a larger audience.
It was really good until chapter 182 and on. I dropped it at 184. The tags romance/harem, idiot and only thinking with his little head should be added so people can avoid wasting time like me.
The name of the book should have been How to pick up 3 year old Chinese girls. It is especially interesting how this 23 year old man in a child's body makes the little girl kiss him by bribing her with candy.
