This is Grade-A 100%-Pure No-Filter power-fantasy bullshit. There is no suspense that the MC might fail, or even suffer consequences, at any time. Only a question of what improbable skill, connection, or knowledge he will pull out of a hat to succeed at his mission, awe the men, and woo the women. The MC's looping power is not remotely explored; just left in the background as a vague explanation for why he can do all this. Yet, I must admit that I am still absolutely enjoying the ride and keep looking forward to the next rabbit to be pulled out of the MC's hat.
Total trash. 7/10. Would recommend.
