Its not about doping at all. Its a mixture about alll you guys said accept for doping. Its about a guy who is an invisble identity and hides himself because he is afraid that world wont understand him. He finds love in a girl. But he loses her (no she doesn't die) and just want to open himself to her cuase she the only good thing he has ever expierenced in his life. Its about have multiple sides to your self and your true self beign the one you usaually keep inside.
