Having fun so far, but there's one major thing bothering me; the MC's moral compass is a roulette wheel.
One moment he's seeing his mother as just another conquest, the next he's going out of his way to take care of her. This is fine, it shows some growth, but then he goes right back to being a manipulative monster to the other girls. He even seems to be going through a similar arc with Hinata, except I'm getting the impression he's just gonna double down instead if Hinata doesn't suddenly decide to close the gap herself.
I'd personally prefer if he stopped being so sexually aggressive with most of the girls after seeing the harm he's doing and tries to make amends. However, him going full bastard is also acceptable as long as the tone is consistent. There seems to be some hinting at there being a choice for the MC to make, but given the general lack of agency it seems more like it'll be a MC choice rather than a player choice. In fact, so far the only choice I feel like I've made is the one to download the himawari patch, and then not to download it for later versions (normally loli stuff doesn't bug me, but the way the MC twisted that girl was actually upsetting, so I suppose good job with depicting a groomer situation).
