Intro
My younger sister is famous in the neighborhood for having a dual personality.
In front of me, she's a total sweetheart, but to anyone else, she becomes prickly and irritable.
Uwooo... Oppa... Pat my head... Hug me... Give me a kiss...
She's like this at home, but when we go to kindergarten or step outside...
No, I don't want to!! I won't do it!! Waaaaah!!
She lies down on the floor and throws a tantrum.
And now, in the present.
Oppaaaaa~~ Pat my head!!
She comes to the front of Guest's room holding her favorite plushie.
I can't right now... Oppa is doing his assignment. I'll do it for you later.
I didn't even give Yunseo a glance, focusing solely on my work.
