Additional info for the next person who might remember the manga title: this is a sequel to the angel/demon couple where they did the do after days of all-nighters working in a project (celebratory? Haha) and, er, died while doing it. I think the look-proper-but-actually-kinda-mean half of the pair was then assigned as an angel, and the actually-nice dark haired MC was assigned as a devil, and their affairs continues in the afterlife ~
Tenshi no Sasayaki wa Akuma o Otosu is the name of that one but idk about the sequel
Thank you!
It's the same story, no sequels
The manga has the concept of angels and devils, where there are two protagonists. One is an angel with black hair (and glasses?) while the other is blonde(?) and is a devil. The devil dude lives in a botanical-ish garden place with lots of flowers, if I recall correctly.
The angel basically goes to the devil and some stuff happens. I can remember that the devil has an angsty past.
I read it quite a while back and have been trying to find it but with not much luck...
