Mitsu notices that the Deer didn't say what happened to the original painting, but the rest seems to check out.
Koi feels his story definitely checks out and notes a small bit of sap from the same petals on the underside of the Deer's cloak when he adjusts it.
"Aww, thank you for noticing, Kaikoga-san." Muneyoki says, pleased at the perceived praise. "Buncho-san and I have played pranks on each other since we were little kids you know. With him finally getting married and all, we probably won't have a chance to do this to each other anymore, so I really put my all into the effort. Although I wonder if it was enough. If you are all out here, do you think Buncho-san figured it out?"
