Ookami to Koushinryou, Mahoutsukai no Yome Recommendations
I cant believe this hasn't been recommended yet. The fantasy genre, the feel, even the music are quite similar. Not to mention romance as a subplot in both.
-European inspired fantasy setting
-Romance between a human and a magical creature
-Chemistry between the two main leads
-Slow paced story
-Focuses on a specific aspect of its respective world (economics in S&W, magic in MnY)
-Themes of companionship
-Atmospheric and relaxing feel because of the detailed background art and serene soundtrack
both of these focus on similar relationships between a human and nonhuman in well-constructed fantasy worlds
Slow paced, great music and character development. Some similar concepts.
Quality waifu and husbando material in both!
I would recommend one of these shows if you enjoy the other because both shows have similar worlds (Fantasy). Both are very heavy on character developments as the storys progress, and both are very good at world building.
