I'm not sure if it's 100% right, but it's basically this. The (A) it's optional. F#m E C#m C#m F#m E You mean that much to me C#m (A) And it's hard to show F#m E C#m Gets hectic inside of me (A) When you go F#m E C#m Can I confess these things to you (A) Well I don't know F#m E Embedded in my chest C#m (A) And it hurts to hold F#m E I couldn't spill my heart C#m A My eyes gleam looking in from the dark and it goes through the whole song.
