No, do NOT go get that motherfucker. For the life of all the people here in this camp, do NOT go rescue that piece of trash. However, something tells me that somehow, someway, that fucker gets a "get out of jail free" card.
Back to more serious matters ... why hasn't the ML had sex with the FL yet? Ah, it's because he has a serious case of beta-mc. Either that or the author want to draw up tension for the NEXT time the FL gets captured by Gamao. Gotta tease that rape (or hell maybe even go through with it) or the whole manga falls on its face, LOL. Then again, in this manga, there's plot armor and plot chastity belts ... some people have it and some don't.
