Based on The Princess and the Pilot Anime (One of my favorites) It includes lyrics belonging to Bts's Serendipity.  A mercenary aerial pilot is assigned a secret mission to protect a former Crown Prince of Sinan whose monarchy was overthrown when the king is betrayed by one of his most trusted officials. The mission is to fly over enemy waters and deliver the Prince to the Kingdom of Levam. However, falling in love was not part of the mission.  

Just a one shot Jikook stories...Based on my ideas...
