"Appa, Saranghae"

Junkyu, who's now a single dad, tries his best to make his daughter, Eunseo, speak again after a year of shutting herself out.

When Junkyu thought her therapy is finally working, Eunseo's teacher called to inform him that she is missing. Junkyu was scared that something bad might have happened to her, but he went home to check if Eunseo was there, only to see a stranger sitting by his door holding his little girl in his arm, sleeping peacefully.
