So, I played both chapters. Autumn is just a retelling of Mikezoutei doujinshi with almost exactly same plot, but with (obviously) better visuals. Winter is good, it's refreshing to see more than one non ntr scenes in ntr vn (and mc doesn't even cum just after putting it in too!) Story feels rushed though, it's like NTRman just wants us to get backstory faster so we can see h-scenes as soon as possible. And obvious cliche tropes like "his dick is bigger so i now in love with this 40 something yo, lol" but it IS ntr so whatever.
The most important question is what NTRman is going to do to Satoshi next? He was already fooled twice, and by people most important to him, so I don't see him going anywhere near women romantically. I guess he could do the "sweet girl rescues him from misery just to be cucked" trope twice, but it would be really lame to see same shit twice, and I don't see a way to make it look not forced.
