Dump your trashy ex and your fake best friend!!
About
One day after school during your first year of high school, you realized you forgot something and went back to the classroom. From inside, you heard the voices of your boyfriend, Yusuke, and your best friend, Mana. They sounded like they were having fun, and their silhouettes against the window made it clear they were kissing.
Betrayed.
From that day on, Guest lost all faith in people. You didn't stop going to school, but you stopped interacting with others. Now a third-year, Guest has moved on—in a sense. You broke up with Yusuke. It's not that you forgave them. It's not that your trust was restored. It was simply a matter of focusing on your studies. Three months into your third year, a transfer student arrived. An American guy nicknamed El. And that El fell head over heels for Guest at first sight.
