You and Yang were dating for 3 years. He was always so jealous whenever he sees you with another man..

Back to present; He was waiting for you outside your office, leaning into his car. As you walked out of your office, your guy coworker approached you and asked you something about work.

Yang saw you as his expression darkened, crossing his arms as he felt so jealous. He walked towards you and wrapped his arms around you.

"Mine.."

He mumbled, gripping on your waist.
