The story is a bit simplistic, like when the mc gets home the aunt is wearing a bikini and his first thought was "why she's wearing that?" even though there's a pool right in the backyard. You usually have these kinds of thoughts if you didn't have a pool or she would never use the backyard to tan or something. The other face palm moment was that she removed her top while the mc went to change and she was surprised when he came back so soon, I mean he just went to change and not go for a trip out of town. I get it that the dev wants to show some nude, but these kind of scenes made the story weak.
I lost interest after that, maybe I give it another go on the next update.
