Mc was kinda ok at first. But now he's just a retard. Not helping when he has these moments: "I'm gonna please these girls with sweet. Hehe, I'm cunny", "oh wow I didn't know" with dumb faces. It's like the author intentionally piss off his readers.
At this point, he already knows average stuffs in modern time are like treasures in mediavel time. He has moments that he thinks he has to be careful, but then slipping on banana peel by doing stuffs that are too abnormal and suspsicous even in modern world. Then making a stupid oopsie face without actually thinking that he did something bad.
He wants to be a trader/merchant but he doesnt really learn nor reflect on his past actions at all. At this point, a normal person will try to be as humble as possible of their valuable items. Learn to properly gauge the value of goods and currencies. I feel sorry for the captain having to deal with his stupid ass all the time.
Also, I can't believe the author just craps on his mc in mere 2 chapters.
