Cover art for Handshake lyrics by Two Door Cinema Club

I believe the last line of the chorus is actually:

"And know you'll always have this if you STAY this man"

She said the devil will want you back And you'll never find love in an open hand Shut your eyes, so you see I'm there And know you'll always have this if you stay this man

I feel like it's about a man who won't change "you'll always have this if you stay this man". If he doesn't change, he won't find love. Going on from toomuch610, you have to work at love and it doesn't just come with a simple handshake per se. The 'She' spoken about in the song is saying to him, why don't you close your eyes, you'll see I'm there for you, but you'll always have this heartache if you stay the man you are.

I dunno, that's just my take on it!

My Opinion

I think I heard the same thing like "And know you'll always have this if you stay this man".

@60_miles_an_hour You're right! Here's the exact lyrics from the official Google Music lyrics:

She said the devil will want you back And you'll never find love in an open hand Shut your eyes, so you see under And know you'll always have this if you stay this man
