I will just share the ED video below from the official source on youtube.  Even though the anime was 2-year old, I just finished the series lately on Bilibili (and actually paid for the premium to access the exclusives).  The ED leaves me with quite a lasting impression.

Storywise, the anime goes is fun to watch along without many twists.  So does the dragon finally find the home in the end?  Here is the spoiler…

ending spoiler

In the last episode, the MC dragon leaves the princess and flies away (assisted by magic) with the wizard. The search for the dream home is still going on. Not sure if the manga also ends with the same note.

Overall, the anime is wholesome to watch.  Especially the life metaphors implied from the encounters along the journey of searching for the dream house.
