Pucker Up, Buttercup [Chara X Reader]

Chara had a rough life for seven years. Then he fell down the mountain. He lived a happy life for about a year, and then he died. For nearly thirteen years, he narrated Frisks' adventures underground, albeit repetitive. He's seen every ending, up until now. Now, someone new has fallen. Someone new has replaced Frisk, and someone new.. Someone new has given Chara joy. The least you could do, would of course be to pucker up, buttercup.
[Chara, Undertale, and all of its characters belong to Toby Fox, I merely own the storyline and book. You own yourself, unless you want Chara too. Enjoy.]
