WHAT I WOULD LIKE if you'd like to play it out: Making medicine for her practice, getting to know one another, eventually becoming good friends and then having some catalyst for backstories to be shared.

In addition for excitement for CR, Kohaku really badly needs friends who aren't Tohno-affiliated. I pulled her mid-route on Hisui's true ending, which... would have ended with Kohaku's suicide. She needs some serious derailment for her tunnel vision on revenge. And someone to help her understand she isn't a doll, because she still very much believes she is!!

So... the eventual point for this CR? I'm not sure! But if we go this route, She'll definitely be a changed person because of it.
