On the 21st episode of KBS 2TV "Bluebird House" (script Choi Hyun Kyung, director Ji Byung Hyun) broadcast on May 2nd, Jang Hyun Do (played by Lee Sang Yeop) and Kim Ji Wan (played by Lee Joon Hyuk) and Han Eun Soo (played by Chae Soo Bin) were put in a difficult situation as Kim Ji Wan (played by Lee Joon Hyuk) caught them in the middle of a date.
On this episode, Jang Hyun Do and Han Eun Soo were having a great time together in the office. Han Eun Soo complained, "You know, I didn't even have lunch because of you." Jang Hyun Do said, "You know, ten minutes is a lot. We're together for the first time in a while. Let's just look at each other for a while" and was affectionate.
Kim Ji Wan was watching this. Han Eun Soo was surprised and stopped Jang Hyun Do. Nonetheless, Jang Hyun Do did not notice what was going on and said, "I'm just trying to have a conversation. Why are you trying to touch me and start something?" Such statement was the last nail for Kim Ji Wan.
Kim Ji Wan said, "You guys let go of each others' hands. What do you think you're doing?" and was angered at Jang Hyun Do. Kim Ji Wan said, "I told you not to meet my sibling. You think you're playing around with her?" and got upset. Jang Hyun Do said, "I'm not playing around but we're just meeting up with each other" and said something wrong. With that, he couldn't withdraw from his statement.
