[Youth campus + male and female protagonists + running in both directions]
Some people appear in life just to prove that loving and staying together are two different things.
We were once so close, so close that we could hear each other's heartbeats; then we were so far apart, so far that we didn't even say "goodbye".
It's not that we don't love each other anymore, it's just that after that summer, we went to our own worlds.
