After their unpredictable meeting, Sunwoo Joon starts to help Goo Ra-ra by paying for her daily expenses, even building a small place for her piano lessons called Lala Land in order to help her get back on her feet.

This is the place where their secrets, pain, stories, and the reason behind Jeon Sun-woo's thoughtful acts towards Goo Ra-ra slowly start to leak out.
