Review Detail of Michael_Uzoho in Assassin's Concentration In Another World

To be honest, the book is alright, I've only read like the first 6 chapters, but so far so good. The only problem I have with this book so far is about the MC. The MC was a 15 yr old assassin, who had no parents cos they died, had no siblings, was raised to be a killing machine, and when he gets Itsekai'd, he meets one pretty girl and he's tripping. I don't understand, there should be barriers that he should have put up, if you get what I'm saying. To shield who he truly was from the others, like how he treats Ordos. But instead, it was like he was an Otaku who has never been with a girl before immediately he saw the princess.
