Byulyi had been spending the past twenty minutes in the toilet, she had diarrhoea all morning and she was convinced she was going to spend the whole day on the toilet bowl. Byulyi's girlfriend, Yongsun, couldn't stay home with her because she had to work on her newspaper column. At times like this, she hated Yongsun for being a journalist. Which is why her sister Seulgi said she'd bring medicine and porridge over to her apartment because her girlfriend couldn't.

Seulgi let herself in as Byulyi told her she'd left the door open. She didn't have the energy to even walk to the door, which the younger woman thought Byulyi was exaggerating.

"Unnie?"

"Toilet!" 

Seulgi set the medicines and porridge on the dining table.

"You can't be serious, unnie."

When Byulyi finished her porridge and took her medicines, Seulgi made her take a nap. The younger woman had wanted to stay with her sister until Yongsun returned, but Byulyi told her Yongsun won't come back until at least midnight.

"I'll be fine, I took medicines. I'll be as good as new when I wake up. I know you have a lot of school work, so go home. Tell mom and dad I said hi."

"Fine, but call me if you feel sick again."

"And what? You'll travel here from Bucheon?"

"Yes."

"Don't be silly. I'll be fine." 

Seulgi finally left Byulyi's apartment after making sure her sister
