Brother/Sister tattoo...??

A guy that is seriously like an older brother to me wants to get a tattoo with my that says "Never drift apart" with an anchor

(I am supposed to be moving to Texas from Erie with his best friend aka my boyfriend) and he wants to get it before I leave. He wants it close to our hearts but I don't wanna be one of those girls with tattoos on her chest. Is there anywhere else I can put it that is close to my heart?

My shoulder blade? So its kinda on the back of my heart and his on the front?
