KOO MUJIN ran after Lee Hajin, who suddenly went off after hearing that Lee Haneum got a headache.
He must be so worried about his appa.
But there was no way he knew where exactly to go.
Hence, Koo Mujin ran faster until he outran his son.
"Follow me, Hajin-ah."
Ah, to be young.
Of course, the Koo Mujin, who was in his thirties, was still healthy.
But being this young gave him extra energy.
Extra stamina, too.
Hence, Koo Mujin didn't even sweat or pant when he finally arrived at their classroom.
Of course, Lee Hajin— who was younger than him— managed to catch up.
"Oh, there are two Mujins," Kim Jaehan commented. "One is a chibi version, though."
Lee Hajin looked at Kim Jaehan and let out a gasp. "Uncle—"
Koo Mujin covered Lee Hajin's mouth with his hand. "Everyone is an uncle and an auntie for this young boy," he said as an excuse, and then he looked at Lee Haneum. "Hey, Haneum-ah. Are you okay…"
Oh?
