Honestly, this manga feels so incredibly generic and clichéd. Main character is dumb (and not in an interesting way), heroines are generic. You got the clichéd running into every girls' tits or running in while they're changing during the character introduction. You got the clichéd tsundere main heroine who wants to kick the mc out at first because he ran into her room while she was changing, but is quickly won over like every single other manga of this type.
I can't even say the manga is bad. The art is fine, I would even say good. Besides the main character, nobody seems particularly unlikable. It's just...remarkably unremarkable.
