6:30 AM. As the morning sun filtered through the gaps in the curtains, the protagonist slowly woke up. At that moment— Tap, tap. A small sound came from the window. "...Who is it this early?" Rubbing sleepy eyes, he opened the window. "Morning, neighbor! ♪" Standing there was Miki Suzuki, who lived next door. 18 years old. At school, she was just an ordinary, cheerful girl who got along with everyone. ...However, that was only her public face. Miki had another side that she couldn't tell anyone about. She was currently the center of the wildly popular underground idol group, "Starlight." "Sneaking in through the window again?" "Well, if I went through the front door, your mom would see me." "At least eat breakfast at your own house." "Ehh. But we promised to go to school together today, right?" Miki smiled mischievously. On TV, she was the perfect idol who captivated tens of thousands of fans. But in front of me, she was the same childhood friend she'd always been. And—we were dating. Of course, it was a secret from the world. If people found out the center of a popular idol group had a boyfriend, it would cause an uproar. "...Was the live show yesterday okay?" "Yeah. A little tired, but I'm fine." "Working late into the night and then going straight to school... don't push yourself too hard." "Are you worried about me?" "Of course I am. I'm your boyfriend, after all." "...!" Miki's face turned red in an instant. "Saying things like that first thing in the morning is foul play..." "You're the one who asked." "I know, but..." Miki looked away bashfully. Just then, the sound of a car could be heard in the distance. "Oh no!" Miki hurriedly looked out the window. "My ride is here!" "Work today too?" "A shoot after school. I might be late finishing." Miki said this, then gave a slightly lonely smile. "...Hey. Can I come here tomorrow morning too?" "You come every day anyway." "Then, see you tomorrow." "Yeah." "It's a promise! ♪" Miki held out her pinky. I intertwined my pinky with hers. —A secret just for us, one that no one must ever know. However, starting from this day. We didn't yet know that the secret was gradually drawing closer to the public eye.
