High Points: President Yoo goes to visit Dad at the dry cleaners and Dad throws him out. Team Leader Kim and Manager Han find out that Soo-young knows the secret, and they make cute plans and a team cheer. Soo-young makes up with her sister, who admits Min-suk never liked her and next announces that she will date his tall friend. He looks stunned but he has seemed to like her before. Soo-young finds Min-suk's photo album and fights him over a naked baby picture, resulting in overbalancing and landing on top of him. Oops! Elf-boy (his name is Jin-woo) sees Dad and finds out that Hung-suk is Lee Jung-soo's son and may be dangerous. He meets Min-suk at the elevator in his high school uniform and calls him by his real name.
What were they thinking? Dad and Grandpa are clearly still mad at President Yoo for whatever happened ten years ago when Mr. Lee drove into the lake. (It looks like he accidently caused Mr. Lee's business to fail.) Pres. Yoo looks like he might want to make amends. He seemed to be looking fondly at Min-suk during their dinner, so why is he so mean to his own son? Soo-young seems to be trying to solve the age problem by having boundaries and waiting. Min-suk, obviously too lively and impatient for that, is pushing her pretty hard.
High Points: We get flashbacks showing Jin-woo following Min-suk around and discovering his secret life. When he meets Min-suk at the elevator he threatens him but says he won't tell yet. President Yoo yells at Jin-woo for being cautious in business deals. He wants to try to have branches all over Asia. Soo-young takes Jin-woo to the hospital when he faints from swallowing pills with alcohol. Min-suk comes to watch over him. (We were trolled by a bed scene in the previews, but it turns out that it was the two guys in the bed, lol.) He answers the phone and finds out that the president is Jin-woo's father. Their dirty secrets cancel out. President Yoo sells a lot of his stock and signs the business deal about the time Jin-woo is finding out that the other company lied to them. Min-suk is called to meet the head of the other company and finds out it is his hyung.
What were they thinking? The managers who know the secret are going a little crazy, Jin-woo is getting suspicious, and his father is greedy and rash in business deals - which is maybe what he did wrong ten years ago. Hyung-suk (Min-suk's older brother) has probably been planning revenge all this time and set up President Yoo to go bankrupt.
