MC adopts a child vampire who ends up growing very fast by consuming his blood and wants to be with him romantically. I did really enjoy this very cute super fast read but honestly kinda uncomfortable seeing a child in one scene and an adult trying to get naughty in the next. Did end with a happily ever after.
Mystical shrine priest will lose his powers if he doesn't marry a member from a certain family and when his fiance runs off he reluctantly accepts her brother as temporary help but they end up in love
