Three pages of a comic of a scene from a fanfiction, linked in the author's comment. The excerpt from the fanfic is:

Kiwi stood up from the bench and cleared their throat. They were smiling shyly at her, an expression they didn’t often wear but Miriam liked a lot. Then they started to sing and Miriam almost regretted asking them to, because her face was on fire and she was sure her expression was absolutely ridiculous. Almost regretted it. (*artist's note: added a "oh no" thought bubble next to Miriam's head in-comic.)

“You’re grumpy sometimes but you still make me smile
every moment with you is a moment worthwhile
I want to spend good days and bad days with you
every day is made better if you’re there too

Whether the world is ending or I’m just sad

(*artist's note: when the comic gets to this point, instead of showing Kiwi singing, a stark-black and white memory of the two of them standing in front of a fracture in the ground, and a black hole in the sky above them, is shown.)

I know you’ll be there for me when it gets bad
when I’m with you I can be truly myself

(*artist's note: a memory of Miriam carrying a sleeping Kiwi on her broom above the clouds in the sky is shown.)

(*After this, the third comic page begins, returning to Kiwi continuing to sing in front of Miriam.)

you make me feel safe more than anyone else

You bring a smile to my face
every time we embrace
when I’m with you I don’t want to go
you’re my very best friend
I’ll be yours till the end
and there’s something I want you to know
I wrote you this song just to tell you the truth
I’m in love with you.”

By the time they reached the end of the song Kiwi had gotten caught up in it, their eyes closed as they sang their heart out.
