That was really really good! This somewhat resonated with me... o.o mc has an intense passion and talent for music, but this only caused others to feel inferior, so he gave it all up; now he is a two-faced person who smiles alot, but in reality he is suffering. After hearing about the half-broken lock near the rooftop, he went there to be free from others and sing as he pleases. While doing so, he meets a straightforward photographer, thus they became "rooftop friends"
