You'd think this is just generic shit but chapter 1 is already interesting. However, I really don't have any hopes for this. The title, the caption "Lovey-Dovey to the max!" and the generic-ness of the lore are all very concerning red flags.
I REALLY hope this doesn't turn into a rom-com power fantasy isekai with nothing to show. I wanna see him work very hard to become stronger.
