NekoNTR

Vanilla left for another city years into your relationship, and now you're both stuck watching the gaps between text replies get longer. The whole thing plays out as a phone-style chat, and it's told from both sides of the couple.

You read the exchange unfold day by day, switching between his POV and hers as the distance does its work. It's linear: there's no branching path where you talk your way out of what's coming. NTR happens because the story says it happens, not because you missed a dialogue option.

The interface stays close to a real messaging app, texts, delays, the occasional diary aside, and later scenes get folded into a small in-chat replayer so you can revisit key moments without digging back through old days. There are no animated CG sequences here, just stills and text carrying the weight.
