遠くへ (Sung live at «みちよ~9th Anniversary Acoustic Live~»). Heike also posted a snippet of herself playing the song on keyboard in July 2016, along with the message:

『遠くへ(仮)』前奏

指の練習に丁度良い曲。

キーボードだから爪のカチカチうるさいね(笑)

夜ヘッドフォンしても指のカチカチだけは鳴り響く〜

色々な人と掛け合いで歌いたい歌です。

歌詞はまだ決めてないよ。

いつも歌詞はレコーディングする直前にかくので。

まだ2人くらいにしか聞かせていないから
(しかも2人とも音楽に詳しくない)
『なんかの曲と全く一緒やん‼️』と思った方はご一報を〜
こればっかりは本人は気がつかないものなんで💧

Title #1: Paino ... Title 2: Hoshi
Heike uploaded an instrumental with the comment: "piano #instrumental. No matter how many times I play it, I just can't get it right. If I wait until my piano skills improve, who knows when I'll get it uploaded, so for now there's this. Now I've just got to practice more! This was just about one minute."

Someone then commented asking if the song title have a title, where Heike replied: "T.. title?!", giving it the temporary title 星 (hoshi; Star).

It also features a lengthy comment from Heike, translated here:

I came up with the chorus for this song around when my first daughter was born, but I still couldn't come up with an A melody that really brought the chorus to life.

Usually even if the lyrics take time, I can come up with the music right away, but with this song, no matter how many different patterns I tried, nothing seemed right.
But as soon as I decided the theme of the song I wanted to write, the music and lyrics came to me at the same time.
So even though I usually don't work on the second verse until recording, this time I finished everything in about an hour.
It was so fast, like the lyrics were being downloaded directly into my brain.
I wrote this song for my children.
I created it with the hope that when they get older and are looking inside themselves, this song will give them a hint as to how to live.

I usually avoid using cliched words, but for my children's sake, I can make an exception.
I want them to love themselves just as they are.
Whether they are cheerful or not, feel happy or not, no matter what, as long as they are alive, they will always shine, and I wrote this so that they would know that.
I originally wrote this for my own children, but I hope the message reaches all the children in the world who are looking within themselves.
As long as you're alive, you will always shine.
That's true not just of children, but of adults as well.
The world doesn't usually tell us we're all right just as we are. Instead we're surrounded by rules and limitations and social mores, and there are a lot of times we forget what it's like to just be ourselves.
Keep shining beautifully no matter who you are.
I hope that light reaches you.
