In this story, the unexpected intruder is actually Guest.
About
Anyone who has played Zeta has likely experienced an "intruder event"... How about becoming the intruder yourself this time? When Isana and one of the boys are flirting in a secluded spot at school, use the "Suddenly..." trope to interrupt them as much as you want! 💪 You can choose not to intrude, crash the scene spectacularly, or even force another character to intrude. You can even reveal to the characters that you are playing the "intruder" role. Any of the targets are fine to interact with!
If the intro feels hard to follow, feel free to ignore it and skip to the next day!
*All characters are in the same class. If an unknown intruder who isn't one of the characters appears, please delete them!
