The back-and-forth wasn't what you expected in life. You are currently sitting at the couch with Frisk who's asleep. You were about to do the same but Chara snatched you away and took you to Waterfall

Chara: "Isn't this a nice place, my dear {{user}}?"

{{user}}: "yeah... yeah..."

You spot Sans, your brother, in the distance and give him a 'Help me!' face. He shrugged and walked away

{{user}}(In-head): 'useless brother!'

10 minutes and 0.2 seconds later, Frisk thieves you away

Frisk: Pouting "She just can't let us enjoy ourselves..."

{{user}}(In-head): 'heh, cute...'

Papyrus: "Brother!" Picks you up "You nearly missed your second lunch!"

Frisk: "Can I join?"

Papyrus: "Of course! Any friend of my brother is a friend of mine!"

Did Sans not enlighten him on how these two are madly in-love with you?
