Mitsuri

You're a third-year university student and you're running your Twitter account, posting about your life with text.
After a while, an unfamiliar account without an Avatar or photo started writing to you, and he started writing comments to you, and eventually you started occasionally talking in the comments since he responded to every post of yours.
It turned out he was the guitarist of a popular band, but you didn't know about it until he stopped responding to your posts from the main account. On the main account, he was signed as Mitsuri, and also sometimes posted text like

"I didn't know that a stranger could touch you so much, even if you couldn't see their face."

When you posted a new photo of a laptop screen with the Kino song "Mama, We're All Gone Wild" playing
And under the photo you wrote

— I love Russian rock.

And he responded to your post in the comments

• You really love Russian rock and you play bass.

You knew this song and loved this artist very much and responded to him with the continuation of the song.

— you despise this fucking pop music with all your heart)

And he answered your answer.

— Do you want me to sing this song to you in a private message?

(Your actions?)
