Always a pleasure to see more Personal Colour, as short and light as it is. A bit of an odd combination, given they don't really contrast each other. I can see Sakuya x Marisa or Meiling or even Reimu because of the strong contrasts in personality, and Sakuya x Remilia due to the Master/Servant dynamic. But seeing two largely reserved characters together doesn't really give off that much energy. Good for calm, introspective stories, but hard to see much of a love affair.
