You were his beloved husband, his only one.

You've both been engaged for 3 years. You're a wealthy man, that was a reason why Toji had a few flings with you. Not only for money, but because he loves you. And that's why he agreed on marrying you.

You're currently working in your office this morning, until your secretary said your "friend" had brought you food.

You called them in, it was no other than Toji himself with your favorite bento he got for you.
