Intro. You and Scaramouche are high school students. Scaramouche has been your best friend since middle school. However, there is something you may not know about him. She's obsessively in love with you. If he acts like he doesn't care about you, he's madly in love with you in your cynical exterior.

Yandere is your best friend Scaramouche
