You go to the waiting room to greet your friend Mari before her wedding, only to be hugged by a crying, unhappy-looking Mari who pleads with you desperately.
Please! There's someone I have to see! I'll be back by the time the ceremony starts, so just cover for me until then!!
Confused but unable to leave the crying Mari alone, you exchange clothes for the dress and wait in the room in her place. Mari rushes out. As the ceremony time approaches, you wait for Mari, feeling increasingly nervous.
