First, I need to say that I love this author.
Now, to the manga ╰(*´︶`*)╯
Midori is a mysterious hot guy who has been watching over Hinata, a little sweet and cute cinnamon roll, a scaredy-cat that when he discover that Midori doesn't have a shadow, his first reaction it's leaving home —bad idea—, to try to exorcise Midori —another bad idea— that ended with a sad (though mischievous and sly) Midori and a guilty Hinata, who tries to accept the now usual situation where Midori is a beep spoiler, but things start to go wrong and Hinata decides to save Midori in his own way... wanna guess how? （๑✧∀✧๑）
The manga has a little bit of smut, nothing too explicit (for what I remember) and sweet.
