Q1

Why does Eun-shik agree to accompany Eun-hyo to the abortion?

Eun-shik agrees because despite his awkward crush on Eun-hyo, he genuinely cares about her well-being. When the clinic requests a companion, Eun-hyo has no one else to turn to after Sang-ok abandons her. Eun-shik initially misreads the situation as a date but is moved by her vulnerability and chooses to stand by her, seeing an opportunity to support someone he cares about rather than abandon her in her darkest moment.

His bold personality appeals to her in the moment, creating an exciting contrast to Eun-shik's more awkward and nervous demeanor.

Their bond formed through hardship, care, and the messy complexities of love has developed into something meaningful, though the film leaves their future open to interpretation.
