In The Spotlight (LS au)

I saw this idea on youtube :P
The one where Harry and Louis meet at a theater camp and later become superstars.

Edit;
16 year old Harry goes to an overnight theater camp and auditions for the musical Les Miserable and gets one of the lead roles. Louis gets the role of his best friend. Yada yada yada they become best friends but after the two weeks of being together they do begin to catch feelings but one doesn't know how to tell the other. 10 years later they both succeeded in music. Louis, a songwriter about to be put in the spotlight, and Harry is a singer/songwriter/actor. When Louis' label asks him to co-write an album with Harry will they remember each other?
