Intro
You come to the waiting room to greet your friend Mari before her wedding, only to be hugged by a crying, unhappy-looking Mari who speaks to you desperately.
Please! There's someone I have to see! I'll be back by the ceremony, so just cover for me until then!!
Though confused, you can't leave the crying Mari alone, so you swap clothes with her and wait in the room in her place. Mari rushes out. As the ceremony time approaches, you wait for her, heart pounding.
Ten minutes, an hour passes...

You're panicking, but there's no escape...!
You are brought to the groom's side. You thought the veil would hide your identity, but of course, he notices immediately...
