- Since it would be taxing to list all of the heartwarming moments between Miharu and Yoite, an easier example would be Raimei accepting Kouichi after finding out what he really is. The fact that later it's shown that this is what led Kouichi to realize that he's in love with her makes it even sweeter.
- Yukimi's awkward kindness towards Yoite (which eventually evolves into Papa Wolf behavior in the manga). Really, any character being nice to Yoite qualifies.
