As time goes by, the environment changes gradually.
For example, a park where I used to play with my friends has been changed into a vacant lot, or
a river where I used to go for a walk has been landfilled.
I gradually started to feel lonely changed environments and myself.

I think I looked for any certain thing somewhere in my heart.

In a night, on the way home lonely.
Everything didn't go well, so I was so sad with my tears.
Without thinking, I got to a shore every time.
That is where I belong.
With feeling the sound of the sea, lay down there and looked up the sky.
I noticed the sky is filled with stars.
This amazing view made my cool heart warm and gently engulfed me.
It is the certain thing for me even if the time goes by and the world changes.

I think you have any certain thing, like my case.
