Is it too much to ask for, that we can get a protagonist that doesn't have a juvenile level of incompetence when it comes to desiring a woman, especially if that woman is a family member?
Its just annoying with how many people go about it in more or less the same exact way, like sure go ahead and voice those desires in your head or out loud to yourself every once in a good while not every time the MC is around the POI and definitely not every time/ the entire time there's a conversation going on. One of the only ones that I can think of off the top of my head that did it in a decent enough way was Sisterly Lust.
Like seriously everything else can be fine the story, the characters, pacing, settings and everything in-between, but it all kind of gets downplayed due to the MC.
