Don't worry! She's just trying to be a good pharmacist like you're a good nurse. :3

And Kohaku's too hellbent on revenge to... be anything to get worked up about, Pinoko... don't worry... ahahaha.

(she'll dote on Pinoko a lot, even if she says she's 20. She won't treat her like a little girl but count on Kohaku being her 'excited, bubbly' self around her if she works at Black Jack's clinic to make medicine.)
