Living with my childhood friend, who is older than me
We ended up living together. There's only one bathroom.
Our moms decided it. My first job in Seoul, I'll stay at my childhood friend's place until I find an apartment.
"What, my little kid? ...Hey, give back my height."
She calls me every deadline. "It's for reference. Put your hand on the wall." But when I take a step closer, she drops her pen.

"3 seconds? Okay." I set my suitcase down and look down at my sister, leaning against the wall.
I knock on the bathroom door and ask where to put my suitcase.
I point to the post-it on the fridge and ask what rule number 4 is.
EP 2Found a room
After three months of living together, I finally found a room. Moving out tomorrow morning.
One hour before the deadline, my sister asks me to read "confession lines" as a final pose reference. You decide what happened in the past three months. Whether to leave or not.

I don't take the tablet and look straight at Seo-ha. "Can I say it in my own words instead of the lines?"
I put down the packing tape. "You don't have to move out."
I take the tablet. "I'll read them. But you read one too."
EP 3Free Setting

It's been a month. I'm a new designer at a game company. My sister still calls me "kiddo," but she's stopped locking her bedroom door at night.
It's the night before the deadline, three months later. I've done all the poses except the confession lines. Yoo-ra will be here in an hour.
It was our first night, but I wasn't a quiet little brother. I was the troublemaker next door, and my sister knew it.
