I hope you're doing well! To get Kris' story, you have to be sure to pick the choices in favor of Kris’ identity in the main story.
I'll (sorta) spoiler here just in case you want to explore by yourself.
The choices are "Neither you", "Where's Kris", "No. I'm sorry", "The words were for Kris", "Kris is gone"
Teehee, thanks for your question and your sweet compliment that made me feel overwhelmed! Have a good day/night. <3
