The person is running close towards her. The more afraid Hana is, because she doesn't know the person. What if that person is a bad person?
Hana then tried to avoid the person. Doctor Jung Woo saw Hana's reaction and thought that Hana didn't want him to stop her from committing suicide.
"HANA. Stop, don't do that!" said Jung Woo trying to reach Hana's hand.
"Let go. Who are you?" Hana asked, scared, because suddenly someone caught her. Almost with Hana's martial arts skills, that person was hit by Hana.
"I'm Doctor Jung Woo!" said Doctor Jung Woo while holding Hana's other arm. His breath hitched with exhaustion.
"Doctor Jung Woo". Hana almost harmed him.
"Why do you want to be so reckless?" asked Jung Woo while looking at Hana's confused face. Jung Woo knows that Hana has trouble recognizing people's faces because of her prosopagnosia.
"Doctor, what do you mean by reckless?" asked Hannah in surprise.
