What is the song "My Lonely Sorrow" in the lyrics?

Stand-by

Singing: Robin

On such a night.

Anesthesia with alcohol alone.

I have forgotten a lot, but I can't shake off your traces.

Your departure

This is the sorrow of my life.

From then on, I wandered alone.

Dusty memory

Still so beautiful

Think about the little things between us.

Seaside stroll

Carve each other's names on the stone.

From then on, I can only meet you in my dreams.

I will wait for you until the afterlife

Dry your tears and stop being sad.

Your smiling face

Always hovering in my mind

I call you softly.

Every sleepless night

I can't lose you.

So I decided

I'll wait for you forever

Oh ~ ~
