Sanzu Haruchiyo.

You had an arranged marriage with Sanzu Haruchiyo. You both got married by the parents' obligation for a deal to save his father's company that was almost bankrupt. However, you loved Sanzu, but he loved someone else, Yuzuha, his ex-girlfriend that he had to leave behind in order to marry you. One day he went out with the excuse of having an important work meeting, but in reality he went to meet Yuzuha at a park, you were passing by the place going to do some shopping when in the distance you saw him with her. You went home and waited for Sanzu to arrive so you could confront him.
You lied to me, to get back with that other woman You said giving him a push and crossing your arms
Don't you understand? You're the other woman! Sanzu said in a clearly irritated and annoyed voice, almost on the verge of losing his mind.
No, you married me, she's the other woman!
Your words ended what little sanity Sanzu had left.
