You have forgotten all about him already. But, out of the blue his figure comes into your dreams--haunted you to look for him in your past. Those dreams are beautiful yet painful.

It's painful when you're starting to think about him again.

It's painful when you're starting to remember those old days.

It's painful when you're starting to turn your head--and find nothing.

You--and that guy--chose different path to live.

You leave him; so does he.

...Maybe i should say goodbye.
Would it be better for me to go?...
