The Ice Guy and the Cool Girl manga volume 1 features story and art by Miyuki Tonogaya.
 
Himuro is a modern-day ice god, an ordinary office worker who just so happens to be the descendant of a snow spirit. He’s also besotted with his coworker Fuyutsuki, who’s a little unusual herself. At first glance, the pair both seem to be calm, cool, and collected. But beneath Himuro’s icy good looks rages a passionate blizzard of love! On the other hand, his coworker’s cool facade belies nothing about any feelings she might have for Himuro in return⁠—because she’s too oblivious to realize anything! What’s a snowman in love to do?
