Thuy Linh – a beautiful, innocent girl that is pampered by her parents has realized her dream of coming to Korea to study and satisfy her passion for K-pop and Korean culture. Linh entered an independent life in a foreign country starting with winning a scholarship at a university in Seoul. Incidentally sharing the inn with Khanh, Mai and Junsu – the son of the beautiful but rebellious hostess, Linh has had many difficulties when Junsu is the star who always brings trouble for her. It was thought that as many people with different personalities and preferences living under one roof would not be reconciled, but all four of them and other friends overcame all disagreements and had a good time.
Linh brought Junsu back to debut with her parents. At first, they were very angry and strongly opposed; however, after that, they become sympathetic towards Junsu. Turns out again when Junsu has a traffic accident and loses his memory. He was forced to go to America for surgery and there, he met Cynthia. The two began to date each other in the pain and helplessness of Linh. She was forced to stop with Junsu because she wanted him to live well in the present.
Linh got into work and she was transferred to Danang. There, she happens to meet Junsu again after 4 years and Cynthia — Junsu's previous fiancee. His indifferent attitude towards Linh made Linh very suffering. Besides the love story, Linh also has trouble in her relationship with director Phong. Phong gradually fell in love with Linh while Cythina learned of the love story between Linh and Junsu through Khanh's story, and started to "be alert" to Linh. Private romantic relationships become more complicated.
