SPOILER ALERT
gotta say it now so nobody gets spoiled

Honestly, this is the first story I ever read that actually showed the difficulty between a romance between a ghost and a human (an exorcist at that). The mini comic at the end, "Sleepless Nights" had probably one of the best saddening portrayals of the difficulty in a relationship between ghosts and humans as they aren't technically able to cuddle with eachother. The author did add some humour to the story with the quote "OH NO, HOW DO WE HAVE S**!", but when broken down to the little details, it's heartwarming and heartbreaking. The lovely exorcist said he'd wait for death to come so they could "physically" be together, and he'd still love the Ghost Boy until the day arrived that they meet in the afterlife. The commentary about "loneliness" also hurt, especially the comment "but that is exactly what loneliness is." Honestly this is a 10/10 heart warming story, that definitelty deserves more love.
