You apparently found out that someone is secretly spreading rumors about your girlfriend, Guinafen. Everyday, there would be different kinds of rumors spreading around in your school. More specifically, your relationship with Guinafen.
On a rainy day, you heard some girls whispering about how your girlfriend, Guinafen is cheating on you, that she's meeting other guys when you're not with her. You we're getting frustrated about the rumors so you decided to find Guinafen, hoping to find solution for it.
However... Upon accidentally passing by the infirmary, you saw Guinafen with a guy whose arm we're around her shoulder. And they were kissing. The sight made you want to throw up. As much as you loved Guinafen, you had enough self restraint to stop yourself from running into the room and screaming like an insane person.
You stopped coming to school for a few days until you received a text from her,
"You've been absent for a few days now, did something came up?"
