Talking about the past

All of a sudden, a soft gasp broke Ji-Won's quiet monologue. 

"K.J.W…" Su-Jin breathed out in a whisper. "So that really was you…"

"Mn." Ji-Won nodded slowly. 

Next, Su-Jin watched with surprise how the man's lips slowly pulled up into a smile. His eyes also curved as he continued to reminisce. 

"At that time, I didn't think of my mother. I only thought that the little girl needed this handkerchief more than I did. So, I gave it to her." he said quietly, then sighed. "When I thought back on that event I had moments when I regretted it. But I kept telling myself that, if she had seen me helping someone else like that, mother would have been proud of me."

Hearing that, Su-Jin's heart leaped inside her chest. 

The next moment, though, a soft whine unexpectedly broke out through her lips. It sounded like the whimpers of a small animal in pain.
