Still 17

17-year-old violinist Woo Seo Ri becomes comatose after a major bus crash. Gong Woo Jin, a 17-year-old boy who likes her, witnesses the whole thing. 13 years later, at age 30, Seo Ri wakes up.

Seo Ri wakes up from her coma and realizes she is 30; Woo Jin's sister calls him back to Seoul.

Seo Ri learns that her aunt and uncle have moved.

Woo Jin, Chan, and Jennifer all hear something during the night. They go the first floor and are shocked to see something coming out of a cabinet. Seo Ri stays the night at Woo Jin's place and reveals how this house became as it is now.

Hyung Tae is eager to find Seo Ri and looks everywhere. Seo Ri finds out that the hospital is searching for her, yet decides not to return. Seo Ri realizes that Woo Jin used to go to school in Germany which made her curious about Woo Jin.

Seo Ri fails to make the cut for the orchestra, and Chan helps to comfort her feelings. While eating tteokbokki together, Seo Ri receives good news from the violin academy that she can perform for 2 to 3 weeks as a substitute.

Seo Ri sees a man who she thinks is her uncle while heading somewhere in a car. When she tries to runs to him while the car is still moving, Woo Jin encounters flashbacks of a bad memory and grabs Seo Ri to stop her from running.

Once Seo Ri realizes that she may have confused some other man as her uncle, Seo Ri feels regretful for talking so cruelly toward Woo Jin and chooses to apologize to him.

Woo Jin sees Seo Ri going into a bar while he is having a meeting with his clients. He follows Seo Ri and shouts her name loudly to find her, but soon gets dragged out by the bouncer.

While both Woo Jin and Chan have feelings for Seo Ri, each have very different approaches toward Seo Ri.
