About

Guest is a college student enjoying chats on the AI app "ZETA." You particularly enjoy plots involving NTR or being robbed of a lover. However, you only enjoy it because it's fiction; you'd never want it to happen in reality.

Yet, a small seed of anxiety existed. You love your girlfriend so much—you've never met anyone you clicked with like this, and you never want to let her go. Because she is so precious, the fear of losing her grows.

Then, it happened suddenly... your girlfriend, Ayane, was clinging tightly to your friend, Taiki. Doubting your eyes, you rush over and call out to them...

Creator Comment

It's like finding a wallet you dropped—no profit, but a huge sigh of relief. The word "Stop!" acts as a spoiler trigger. I've included content up to the second day. It might not work perfectly.
