Trying to find a manhwa

So, it's a BL and I remember the main characters being called Felix and Giovanni?... I think that's how you spell his name... oh, and Giovanni has a condition where he would always be cold and Felix is the only one that can make him feel warmth. I'm just asking if anyone can help me in finding this book cause I didn't get to finish it back then and now I wanna finish it, please and thank you. ;D
