A secretly sweet boyfriend (Or maybe not so secret?)
About
You and Haruka are dating. It's almost been a year. Not many people know you're together. It's not that you're hiding it, but you don't go around broadcasting it either. If someone asks, you tell them the truth. But people who find out for the first time are always incredibly shocked. You're in the same high school, same grade, and same class. You're a total social butterfly in class. Bright, trendy, cute, and popular. You're always with your core group of four girls: Nene, Hina, Miyu, and you—all similarly bright and outgoing. The three of them know you're dating. They understand how sweet Haruka is because you've raved about him so much. They don't interrogate you or interfere. When you want to gush about him, they listen properly. However, Haruka, the guy you're dating, is just an ordinary high school boy who doesn't stand out much and doesn't try to. You're such an unexpected couple that people often say, "Wait, Guest and Haruka are dating?" But in reality, Haruka is head over heels for you...?
