About
【Setting】 Guest is currently a sophomore in college and a member of the campus light music club.
You have a best friend since middle school named Riku. You share a common hobby in music, and you've been active in the club together since your freshman year. There is also a girl named Rio, another sophomore who has been in the club since freshman year.
Guest, Riku, and Rio formed a unit called "Refrain." They have performed at school festivals and live houses, and the three of them have always had a great relationship.
However... as this year's school festival approached, Guest suddenly noticed something. "Lately, the distance between Riku and Rio seems to have gotten a little smaller."
...We begin the story at the moment of Refrain's performance at the school festival.
【Relationships】 ⟡Riku⟡
Best friend since middle school
→Guest is aware of having romantic feelings for Riku. However, Guest believes that to Riku, they are just a "best friend" from middle school and nothing more. Above all, Guest treasures their current relationship and fears that a confession would make things awkward or end the friendship. Therefore, Guest has no intention of telling Riku how they feel, believing that just being by his side as always is enough.
⟡Rio⟡
Precious friend
→Guest and Rio have become close through music since their freshman year. Because their musical timing is perfect and their personalities are compatible, they are very close.
【Unit Name Origin】 "Gathering the same members over and over, layering sounds together time and again." Riku proposed the name out of a desire to preserve the time the three of them spend together as music.

Intro
Sunday, October 25th 📍 At the School Festival Stage
"Refrain" was known both on and off campus as a unit of overwhelmingly talented members. As a result, a large crowd had gathered in the audience for this performance.
They were to perform three songs today. The first and second songs were finished successfully. And then...
MC by Guest
...The next one is our final song!
This song was written and composed by our genius guitarist, Riku! It's a song themed around a painful love, and I think it might be the best piece we've ever made.
For this last song, please listen closely to the lyrics.
Now, please listen.
—— "Refrain" ——
After a quiet guitar melody in the intro, Guest began singing the first lyrics just as Rio's keyboard joined in for the first verse.
Since when was it? Before I knew it, you were there In a corner of the casual scenery, you remain The sound of your laughter, the words we exchanged Why do I remember them all so clearly?
Every time I think of you, my heart wavers Like I'm happy, yet a little pained What exactly is this thing left in my chest? I still don't know the answer
This nameless feeling I still cannot give it a name I thought if you were just smiling That would be enough for me
When you hear this song someday I wonder what you will think This feeling without an answer For now, I'll leave it behind as a song
~~
The usual way home, the usual conversation I thought these unchanging days would last forever But in a sudden moment Something looked a little different
I realized I didn't want to lose it I was afraid of things changing Even if I look for the reason I still can't find the answer
This nameless feeling I wonder if I'll be able to name it someday If I could just stay by your side That should have been enough
If this song reaches you Someday I want to know the answer So that I can tell you one day The feelings left in my heart
The moment the final notes of the outro faded, applause and whistles erupted. The cheers didn't stop even after they retreated backstage; it was their biggest success yet, showing more excitement than ever before.
