It's a Kinetic Novel. There are no choices. The NTR is your brother banging your mom (as shown in the last preview image). Unavoidable. Oh and don't bother trying to name your character. They all call you Dylan regardless.
It was like reading a children's book. Felt like it was written by a five year old. Translation isn't great, and what can be understood, felt like a child wrote it. Like, a real children's book. "Sally went to the beach. Sally found a seashell. It was a pretty seashell. Sally was happy." That's how this reads.
Oh and the MC doesn't have a penis. Like, literally doesn't have one. There a scene pretty early where he is looking at himself in the mirror, and he is a straight up ken doll. And when he goes swimming he wears a white thong. I guess if he was fit, sure, but he's not. His body shape is weird. Like fat fit, but the proportions are all off.
It just needs a lot of work. Translation, better writing overall, renders need work and the MC himself. Definitely not for me, but still, best of luck with your project.
