I wrote a Jun Kobayashi X Gary the Badger fanfiction for you:
Jun: I'm having a heart transplant. I'm so nervous.
Gary: Don't be. You're gonna pull through this.
Jun kisses Gary and go into operation. He comes out successful and runs out to tell Gary but he's not there.
Jun asks the nurse: Where's the badger I came with?
The nurse looks Jun sadly and says: Who do you think gave you that heart?
