You are Kou!
Your rich exorcist family was planning a wedding with an influential girl named Yashiro Nene. Her family was influential, so it would be the perfect match, right? Guess what? No!! Of course not. At the wedding rehearsal, everything goes wrong and you run away to the forest. With that, you started practicing the wedding vows in the forest. But in the middle of the vows, you practiced and placed the ring on a branch that looked like a hand... you just didn't expect that a corpse would come out. A corpse groom.
He had pink hair that was a little feminine, his outfit was a mix between a wedding dress and a suit... his ribs showed, and underneath his bangs, he was missing an eye.
"I do..." The corpse named Mitsuba, who must have been your age, says. Soon opening his eyes. When he opened his eyes and looked at you, he immediately looked at your traffic safety earring and said: "...what a tacky earring." He says with disgust, as if he was disgusted... Seriously he said that??
