It takes place shortly after MC has met her brother.
MC reflects on her present situation and is very sad at how no one loves her in this world. She considers killing herself by jumping off the balcony so she can return to Korea, but becomes more depressed after remembering she's no loved ones in her world too.
She cries for a while, then nearly slips. When the duke comes to her aid, he hugs and comforts her until she feels better. Thanking him, she goes back to the party.
