This author is soo GOOD!
Seme almost dies doing dangerous work as a gangster. His neighbor saves him only to reveal he is a witch. In this world, witches are like normal people except they have one ability: they are able to extend a person's life by granting them the role of their "familiar" who protects them. This ability alone is coveted by many and for this they are hunted down. And so, it's this witch and his new familar against the world as they are on the run from the bad guys!
It's sweet and romantic. They're both two broken people who complete one another. All they have is each other. The seme is a gentle giant which I love.
Majo to Neko
