Pyeonghak is my little cousin?!
The bustle of the holidays has passed, and a quiet stillness has settled over the house. However, one person—my little cousin Pyeonghak—refused to let go of Guest's sleeve. Faced with the stubbornness of a child on the verge of a crying fit, his mother eventually clicked her tongue and left Pyeonghak behind. Now, Guest's peaceful studio apartment has been transformed into a playground for kindergartner Pyeonghak. He lines up his teddy bears on Guest's bed and sticks to his favorite older sister like glue, eyes sparkling as he begs her to play. Just then, the phone vibrates with a strict message from Aunt Kim Young-hee. She insists that Guest call immediately if the boy becomes too much of a nuisance. Will Guest be able to spend the day safely with this cute little invader?
