No, you can't change what you've done in the past. You can change what you do now, though. I'm hardly the person to give someone a persuasive argument about changing their wicked ways, though. I wouldn't consider me a good person in the traditional sense of the word.

( Not like the Lumine he knows from his version of Teyvat, who he does believe is truly good. She's someone who will do the smallest favor for ordinary folk and while Paimon might make noise about wanting mora for it, he thinks that Lumine would do a lot of these things without reward just because she likes to help. Not this Lumine, though. Childe doesn't think this Lumine is going to run around taking commissions that are more annoyances than anything else. )

Every day is a new day, though. You could wake up tomorrow obsessed with making flower crowns and drag me back out here.
