Koori Zokusei Danshi to Cool na Douryou Joshi is a cute wholesome manga that follows the life of the two main characters, the Ice guy or descendant of a Yuki-onna, Himuro, and the cool female colleague, Fuyutsuki. The story centers around the daily interactions between the two while working at their office, where Himuro is usually so smitten with something Fuyutsuki did. Every chapter is limited to a few pages but these few pages are enough to completely capture my heart and make me go 'awww' every time. Sometimes, we also get to see a few glimpses of interactions between their other colleagues (there's a fox descendant and a phoenix as well!). The story also shows their hardship for being a yokai descendant and how they try to live with it (and slowly finds the beauty in them from their partners)
If you want to read a simple, wholesome, and chill romcom, this is definitely for you!
