Exactly this. Chad is like one of those overly perverted "best friends" of the MC in anime, like High School DxD, and while it's fine in moderation...that's his whole ass character and it's nonstop except for maybe 1 or 2 spots. Now, the MC is just as perverted, ain't gonna lie, but he knows how to keep it in check for the most part and does it in a more playful manner and with the girls who like him back and kind of like it.
