The premise is he (Himuro) drops the temperature of his surroundings and even causes blizzards when he either is concentrating or when he's thinking about the girl he likes (Fuyutsuki). But everybody else is okay with this ability of his like it's normal, maybe a little inconvenient, but everybody likes the guy enough. This description does not even begin to portray how amusing the situations were in this series, amusing and so cute.
The chapters are very VERY short, like 2 or 3 pages each. Each chapter feels like a 4-koma even but with a lot more detail obviously, both in dialogue and artwork.
The characters are obviously not too deep because they don't have to. All you need to know is the guy's "curse" and how he is sweet. His crush, Fuyutsuki, somewhat is like him as well as to how she doesn't seem to show much emotion, but she obviously cares for our main guy and is always helping him out with his unconventional daily struggles.
The artwork, considering the nature of this series, is proportionally gorgeous. It rarely (if ever) uses chibi style. All the characters are gorgeous looking. Our girl, Fuyutsuki, though looking plain Jane, makes my heart skip because she's just pretty.
You can breeze through the whole thing in no time, so enjoy!
