On the episode of KBS 2TV Monday/Tuesday drama "Who Are You - School 2015" broadcast on May 19th, Han Yi Han (played by Nam Joo Hyuk) got into a love triangle with Kong Tae Kwang (played by Yook Sung Jae), and Lee Eun Bi (played by Kim So Hyun).

On this day, Han Yi Han (played by Nam Joo Hyuk) was on his way to school when he found Lee Eun Bi (played by Kim So Hyun). Lee Ahn ran to Eun Bi and said, "Hey, why didn't you come to morning exercise?" At this, Eun Bi said that she overslept. Lee Ahn said, "Come to morning exercise tomorrow. I don't want to run alone" as he tried to be cheerful.

At this, Lee Ahn said, "Do you want to go watch a movie after you get done with training today?" With that, he mustered up the courage to ask Eun Bi out. Nonetheless, Kong Tae Kwang (played by Yook Sung Jae) appeared and said, "That's good. What do you want to go see?" and answered instead of Eun Bi.

At that time, a motorcycle appeared and at that time, Lee Ahn put Eun Bi into his arms and protected her.
