I recommend a book called "Wildfire Burning Green Clouds". This book is a fantasy romance novel written by the author, Green Water Looking Forward to Green Mountain. The male lead, Leng Qingyun, was a little dark and cold. He was born to walk with the darkness, while his partner, Yuan Ye, had his own wildfire and was a professional lamplighter. The team formed by the two of them roamed the Otherworld Continent, braving the wind and waves. I hope you like this fairy's recommendation. Muah ~😗
