No matter where you are, you'll always be in my heart.
No matter where you are, there will always be a place for you in my heart.
No matter where you are, I'll always treasure you in my heart.

不妨这样说，No matter where you are, you will be in my heart. 不用非得说那个"角落"的。

No matter where you are, there will alway be a corner for you in my heart

No matter where you are, you will be a corner in my mind
