Am I my love's main cast?

Thought my life was dreary,

You fell into my cloud ordinary.

Thought You're the one,

You fell for me like a movie.

Thought you confessed to me,

You fell for my best friend.

Thought It's over,

I swallow my sorrows in front of you,

I bury my pain with tears at night.

I pretend I'm fine,

I soak my pillow at night.

You said she's the one,

You asked me to be gone.

I'm only a supporting role.
