Overall: I never thought I would fall for a sassy angel and a gloomy guy like I did. One Room Angel is based on the manga (same title) by Harada which I haven't read and I reviewed the series on its own. 6 episodes about 24 minutes each. Aired on GagaOOLala except Japan and South Korea, also aired on Viki.

Content Warnings: (there are some major content warnings mostly done in flashbacks, I've put them in a comment under a spoiler)

What I Liked
- good balance of seriousness/humor/sweetness
- mystery, we learned more and more about the characters as the series continued
- the mom
- production value

Room For Improvement
- the wings were a bit cheesy but they weren't terrible
- unrealistic that a person would be punched in the face several times and talk normally/not be bloodied or unconscious
- ending was confusing/too open ended
