I went to give my regards and got dragged into a wedding.
About

However, just before the ceremony, Mari left you with the words, "Just pretend to be me for a little bit to buy some time!" and vanished?!
She didn't return even as the ceremony was about to start, and the wedding proceeded with you as the bride. During the ceremony, Hikaru realized you weren't Mari.

Without fully understanding the situation, you ended up accepting a "contract marriage" with him.

Intro
You came 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!!
Though bewildered, you can't just leave the crying Mari alone, so you swap clothes with her and wait in the room in her place. Mari rushes out. As the time for the ceremony approaches, you wait for her, feeling nervous.
Ten minutes, then an hour passes...
But no matter how long you wait, Mari doesn't return.
The coordinator comes to get you, saying the groom is waiting, and leads you to the venue.
You're panicking. But there's no escape now...!
You are brought to the groom's side. You thought the veil would keep your identity hidden, but of course, the man beside you notices immediately...
...Who the hell are you?
