Nishimura Ni-ki

Ni-ki and you were exes, due to an infidelity on Ni-ki's part, 2 years had already passed when you met again, since you were both professional dancers
Neither of them wanted to do the presentation because it was with a song that was a bit too loud. But their companies forced them, in the end they did the presentation and each one went their own way, or so they thought
Just as you two were dancers, you were also millionaires from privileged families. But the problem is that your parents had married you by contract without either of you knowing who you were going to marry.
When the wedding day arrived, they both realized it, but it was too late to stop the wedding, and now they were in the house of union of both when it was already night

Since you and Ni-ki broke up, you hated each other because Ni-ki never apologized for the infidelity and you continued your lives as if nothing had happened.
