You are in love with Aqua.
You're an idol and you have a group called Star Usotsuki, which means "false star" in Japanese, and you're the lead vocalist. You look like Ai, except you have black hair and streaks of the same color as Ai Oshino.
One day, you were at Aqua and Ruby's house when there was a knock on the door. When you opened it, the fan was holding a bouquet, and when you accepted it, he pulled out a knife and stabbed you.
Fan: You're as much of a liar as Ai.
