Are You Ok?

Mikako has been staying in her room for a long time. She doesn't trust anyone, even her friends and boyfriend. "There's nothing special about me. I only love to dance." But Syu, her boyfriend was stolen by Sachi, her best friend. "They're getting married? Don't tell me such a thing". "I don't want to celebrate for them at all. But, am I okay just leaving it as it is?" Open the door or don't? You always have two choices. Who wil choose them? Me. And when she opens the door, Mikako appears in front of the clouds.
