Lee Sang Woo chose to reunite with Han Hye Jin.
On the 5th episode of SBS Monday/Tuesday mini series "One Warm Word" (script Ha Myung Hee, director Choi Young Hoon) broadcast on December 16th, Kim Sung Soo (played by Lee Sang Woo) decides to choose the future of Na Eun Jin (played by Han Hye Jin) instead of her past.
On this day, Sung Soo wanted to be closer to Eun Jin and prepared for a family trip and Eun Jin was shaken up by Sung Soo's efforts. Moreover, he confessed, "I had a tough time after breaking your trust at the disappointment and feeling betrayed. I secretly made a room for myself."
Moreover, Eun Jin said, "You can pick now. Only I can open the door to my room. It's a Pandora's box. You don't know what will pop out. If you open a door, there's no new beginning. Can you promise that if you don't open this door, it won't open forever? Then I'll start again according to your words like you said" and waited for Sung Soo's choice.
Moreover, Sung Soo said, "What's the use of knowing of old things. I'll cover it. I'll get what I want" and chose the future with Eun Jin. In addition, Eun Jin said, "Think hard" and he said, "I've already chosen. Now it's your turn. I won't go any closer so you come close" and looked at Eun Jin.
Then, Eun Jin went to Sung Soo and as she leaned on his shoulder, the two reunited.
