Park Suh Joon protected Kim Ji Soo in front of Ji Jin Hee and Park Suh Joon.
On the 6th episode of SBS Monday/Tuesday mini series "One Warm Word" (script Ha Myung Hee, director Choi Young Hoon) broadcast on December 17th, Song Min Soo (played by Park Suh Joon) raised his voice for Song Mi Kyung (played by Kim Ji Soo), his sister, who was just getting defeated.
On this day, Yoo Jae Hak came home drunk and Mi Kyung said, "How can you be so proud after having an affair. Do you think it was easy to be someone's daughter, wife, and mom? Do you know what I did to catch you? Do you know how much I despised and hated myself?" as she fought with Jae Hak.
At this, Lady Choo (played by Park Jung Soo) said, "I can't look after you any more. You're not living in here by yourself. How can you make it known that you have no base? Why are you making it such a big deal that a man had an affair. What did you do in this house?" as she got upset. At this, Mi Kyung just cried.
Min Soo came home and watched this as he approached Mi Kyung and said, "Why couldn't you say anything?" To Lady Choo, he said, "I'll say one thing. She said to someone who worked from 5 a.m. for twelve hours that you had done nothing."
Lady Choo said, "They said to never take in a person because they'd betray" and was dumbfounrded but Min Soo said to Jae Hak, "Brother, whatever sis said, couldn't you take in a person that was so drunk that he couldn't take care of his own body?" as he carried Mi Kyung to the second floor.
Lady Choo then mocked Min Soo because of his strong expressions and ended up being critical as Jae Hak ended up exploded and screaming, foreshadowing yet another conflict.
