The beginning of this story is so off-putting with the main character just being a pervert
I'm afraid that's the jumping off point of this story.
Your MC hasn't suddenly discover his feelings for the others, then half-heartedly struggled with those feelings until he accidentally spies them soaped-up in the shower (which is why the obligatory shower scene is dealt with immediately).
You join him when he's horny, frustrated and wants to see some skin, and his judgement has been... questionable. Which could lead him to a lonely and grizzly end. And that's up to you.
Interesting though. He's accused of doing the same stuff that's fairly common in most VNs of this type (spying, creeping, toothbrush molestation etc). Do you feel he's slightly unplayable now, even though you may have made the same choices that led him there?
Let's hope you stick around to see him grow and change.
...No promises he will though.
