Four-leaf

Susumu and Mirai - friends since childhood. They spent time together while their parents were busy with work and business trips. All is good, but Mirai fell into a coma.

Susumu visited Mirai in the hospital, and in spite of what was already a year, nothing had changed. One morning, Susumu discovers that he can not leave the house because all the doors and windows are locked. He decided to go to bed, because nothing could be done, Susumu falls asleep on the couch. In the morning he wakes to a strangely familiar voice,

"So, how long will you sleep?"

Mirai is standing next to the bed.

"How did you get here?"

"Please, don't ask anything. It does not matter. I'll tell you after... now, let's make a date?"
