"Lee Yeong-Cheol!" The woman's voice called out loudly.
As if on command, both the little boy and Seo-Jun turned their heads in the direction of the shout.
The moment he saw the young woman running towards them, the little boy's face lit up and he launched himself straight at her like a missile.
"Big sister!" he called, burying his face in the woman's open arms.
"Yeong-Cheol, what are you doing here? You were supposed to wait for me outside." The young woman softly chided the little boy.
Meanwhile, Seo-Jun remained rooted to the spot. The only thing he could do was stand there and watch as that person picked up the small boy and slowly turned her head sideways. The moment he caught a glimpse of her face, his features transformed into a mask of shock and disbelief.
Just then, she suddenly noticed the presence of someone else and she turned her head. The instant her eyes landed on Seo-Jun, her expression turned stiff.
