One Fine Day - 1x04 - Episode 4- Followmy.tv

Sung-chan stops Gun from hitting Tae-won and Ha-neul looks at Gun, surprised by hearing Sung-chan calling him Gun. He angrily takes hold of Ha-neul’s hand and takes her out of the house. Ha-neul asks him if he really is Gun, her brother. Gun gets angry. He yells at her asking her why she didn’t run away from Tae-won earlier. And at this she just hugs him from behind and thanks him for not forgetting about her and coming back to find her. Gun brings Hyo-joo back to Sung-chan’s place. Hyo-joo, Kyung-taek, and Sung-chan all sit down and talk. Thoughts of Ha-neul keep bothering Dong-ha, and he asks Sun-kyung if Ha-neul still hasn’t shown up for work. Gun goes to the hospital that Soo-hyun is at and politely introduces himself. Ha-neul returns the paycheck that she got earlier than she was supposed to back to Dong-ha, and tells him that she will quit. But Dong-ha asks her if she would like to take a diving course. Hyo-joo comes back from the groceries but ends up overhearing Sung-chan and Kyung-taek’s conversation. From hearing their conversation she finds out that Ha-neul and Gun are not exactly brother and sister.
