Tear Jerker / Nice Kaachan AU

• Amnesiac Katsuki's reaction to learning what he was like before the memory loss.
  Bakugo: No. No way! This can't be me! What is this?
• He then pleads with the others to tell him if anything they told him about how "nice" he was before was true. The worst part is that he can't even apologize to Deku about what he put him through, because Deku knows that once his memories return he'll be furious about it.
• The "nice" Kacchan finally disappearing. His instant switch in the middle of his farewell speech from "nice" to "I'm going to kill you all for being nice to me for a week" is supposed to be a "oh, good, Kacchan is back to normal" joke, but that's in the eye of the beholder.
