Aww, very cute. "Lily becomes a human so they don't have to deal with contract or life span stuff" was kinda what I was expecting to happen from the beginning, but I think it's a good way to end a story which is as fluffy as this one.
...Although, I'm still unhappy that this came at the cost of zapping the other main plotline (namely, building up to where when and how Mai and Lily are finally gonna have their first time). I wasn't expecting anything crazy explicit, but when a bunch of the plot is dedicated to teasing that sort of thing I was hoping for a bit more than timeskipping past the entire resolution.
Anyways, thank you to the scanlator for your time! I've had a lot of fun reading this over the last few months. If you hadn't said anything, I definitely wouldn't've known this was your first scanlation. Keep doing great work!
