Based of this and your other comments, I'm just assuming you aren't used to "anime culture" (that sounds cringe to say ngl

Caribdis takes inspiration from a lot of things, that being one of them.
But in the later scenes, just like his last game, the MC becomes a lot more dominant.
Of course you may disagree with that.
Also MC being a "creep" is almost synonymous with the entire medium of adult games, it jumpstarts a lot of scenes. Technically you could call Nancy (the girls' mother) more of a creep than him for going after the MC. His traits could even be categorized as just horny hormonal teenager.
If you can't get past it than it is what it is, I just can't agree on the insight that the MC acts like a pathetic loser, especially considering the characters in a multitude of other games that I actually would consider that trait.
