You've read the story a thousand times before; some random schmuck gets isekai'd and ends up with an overpowered system. However this time, something seems off about the protagonist.

"You do understand the absurdity of wanting to be a harem protagonist, right? I mean; do you have any idea how emotionally draining it'd be to have multiple women vying for your affection? In all honesty, you'd be much better off just picking one of them and letting the rest down slowly. Because if you remain indecisive for too long, Makoto's fate is the only thing that awaits you."
