CEO's Contract Wife

Imma give it a try

Don't like fanfics usually but this one is pretty good

I find it to be quite a nice read.

author is a sick p*rv*rt but outside of that his writing is amazing

his strength is basically relied on the other world character of his, if the character he becomes is a kid then his stats are for a kid, but whatever knowledge he obtains will still be accumulated but skills that are more of working due to the body won't be brought over to the new world. but more or less he is like grinding on side quests on this world as the main plot is in his real world where he gains everything he gained from the other worlds
