Kim Yo-han embodies Kang Min-haka modeling student and rising star on the social networks. He became famous after an acclaimed appearance on a dating show, and now has over a million followers. Charismatic and magnetic, he's a real eye-catcher... but behind this perfect image lies a surprisingly simple, almost naive young man.
At his side, Hwang Bo Reum Byeol lends his features to Ju Yeon-sanfirst in her class in computer engineering. Brilliant, fast and methodical, she is capable of solving the most complex problems. But the slightest mistake and her "system" collapses, revealing its fragility. She has no experience of love, until the day her path crosses that of Min Hak. Their meeting becomes the spark for a romance that could well rewrite her "love algorithm".
