She walks away wishing that he stays miserable forever.

Meanwhile, Baek-ho and Mi-kyung go on a ramyeon date by the Han riverside, where they spot an intoxicated Hee-jin drowning her sorrows. She quickly joins them and reveals her love story, describing how she attended a training program, met Ki-se, and became smitten with him.

She rushes to Ong-ju's place to set things right and is joined by Baek-ho. After a hilarious trespassing attempt that lands everyone in the police station, Ong-ju and Mi-kyung reunite as she gives her blessings to Hwang-kyung and her relationship. Ki-se, on the other hand, reflects and wants to settle things with Mi-kyung.

The next morning, Mi-kyung wakes up to the news of Ki-se's father passing away.

After a while, she leaves him to return to the office as Baek-ho sits in his car, witnessing everything. He does not come out and show himself to Ki-se or Mi-kyung.

Baek-ho feels guilty because six years ago, CEO Yoon asked him to discreetly handle Ki-se's ex-girlfriend. He did not realize that he had been a catalyst in driving Mi-kyung away from Wonhan, allowing Ki-se to marry Hee-jin in peace. As the truth finally dawns on him, he is ridden with guilt.
