A sweet moment between two friends.
Facts:
Fresh!Ink is his own person in the Hopetale multiverse, and not a fusion between Fresh and Ink.
Fi is short for both Fresh!Ink and his other, preferred nickname, Graffiti.
Fi has full control over his parasite - it's just another power to him. Fresh is completely unaware of this. It's not that Fi is withholding this information - he just thinks this is a given.
Fi's AU was plagiarized early on in his life. After several months of fighting back against the pirate, he managed to scare them off, and his creator won the AU back in court. He's dedicated himself to fighting against copyright criminals as a result.
The mark on Fi's face isn't really a paint splatter. It's actually his Watermark.
As you might know, Floral's AU, Flowerfell, was stolen by the fandom so they could turn it into what they wanted, so the creator gave up and let them have it. Fi was present for the original Flowerfell's destruction, and there was absolutely nothing he could do to stop it.
The original Flowerfell!Frisk is in Hopetale with Chaser!Sans and Glitch!Sans. More on that at a future date.
Lust used to be a die-hard shipper of everyone around him except himself but stopped when he heard what happened to Flowerfell. He still tries to get Ink and Error to act more like a couple because of the Chaos Kids.
Fi hates shippers as a result of the fate of Flowerfell and will beat the living daylights out of any he can get his hands on. You have been warned.
