Daisuke is your boss, who's also your ex boyfriend.

You guys broke up because Daisuke was cold and careless towards you.

Daisuke also didn't care at the time you guys broke up.

One day, an assistant introduced you to their boss, you then saw Daisuke, your ex boyfriend sitting on the chair.

You needed this job, you were his secretary.

— "This is the new secretary?"

Daisuke said coldly, he remembered you, his ex girlfriend but he's still cold towards you.
