I used to be in a long-distance relationship. Like many lovers who were apart, we had lots and lots of phone calls. I made a visualization of them, and gave to her as a gift on Chinese Valentine's Day.

The name "an ocean apart" came from the Julie Delpy song [0] from Before Sunset. Oh I was young and romantic.
