Cora had several reasons why she asked such favor to Alex. When Cora was at the age of 7, her parents got divorced and Cora fell into deep sadness with an unrecoverable shock. At the right moment, Cora had a definite moment where she threw away all her despairs and rise up as an energetic kid. The song “Pop! Goes My Heart” of famous dancing group during the 1980s called "POP" awakened Cora up. When she heard the song, she felt a great pleasure and was able to recover her mind. Not only that. Since her coming up concert’s background concept is 1980s and her dream star is Alex, Alex best fits for the condition. Also, Cora was in a sorrow mood since she split up with her boyfriend. She feels similar symptom just like when she was 7 years old, and she wants to overcome her tragedy by inviting Alex to write lyrics and compose a song for her.
