Review Detail of JR_989 in Reincarnated as the stepson of a mafia mob [BL]

The story has potential in my opinion, but the protagonist seems to overpowered (He is a person, who has a very high position in the military, is a well-known artist and a highly successful game designer etc.). Furthermore the text switches between tenses, which does not work out. The idea itself and the storyline- from what I have read- are rather charming, therefore a few plus points are given.
