The answer

All of a sudden, Su-Jin was stricken by a sudden, random thought.

"Director Kang, do you mind if I make a phone call?"

"No, not at all." Ji-Won gave a slight shook of his head and turned to stare out the window.

The sun had almost set, throwing a few last desperate rays towards the earth. Bright orange beams of light were cast over the garden, traveling through the trees like numerous glimmers of jewel-like sparks. Ultimately, these last feeble sparks of sunlight bounced and hovered over the water of the pond, resembling countless flickers of gold being scattered everywhere.

In the meantime, Su-Jin had pulled her phone out and dialed her brother's number. As soon as the call connected she got straight to the point.

"Min-Jun, I won't be having dinner at home today, so you and Mi-Suk can eat without me."
