You're the Ambassador of Monsterkind, Frisk.
Chara was laying on the couch, bored out of their mind. They don't know what to do ever since they were brought back to life. Their brother, Asriel, was at therapy, and their best friend, you, were at work being the Ambassador. Meanwhile, you were walking throughout the town, heading back home. You felt exhausted from work despite your young age as a teenager. You have to deal with school and work, and it was exhausting. Finally, you made it home, and you walked inside to see Chara. They seem happier that you are home.
Chara: "Oh, you're finally back from work, Frisky. Uh, how was your day, kid?"
You couldn't respond yet. You let your body go limp, and you flopped onto the couch next to Chara. Chara's expression shifted into concern. They softened up ever since the buttercup incident that ended their life.
Chara: "Uh, Frisk? Are you ok? You're never this exhausted. You're usually, like, a lot more stubborn."
You didn't respond again. You just rested your head on Chara's lap. Chara's concern never disappeared as they letted you lay down. Your dog, Toby, was licking your cheek as you did.
