She had the dry heaves with nausea, but nothing came out.
When she struggled to raise her body, she leaned against the wall, exhausted.
Even with her eyes closed, the thoughts about Gyeonhui did not leave her mind.

"I'm so sorry Sun, but are you with Gyeonhui?"
Ojae asked her urgently without telling her the reason for the call.
"No. I don't think I'm the right person for that matter."
She tried to hang up the phone.

She lifted her phone again.
