Chéri, My Destiny!
Chefs kiss...? Do.... do they really? Kaoru is a western style chocolatier, with a one-sided rivalry with Japanese confectioner Sojiro. Once they get to know each other, Kaoru realizes he's in love, BAD. (Side note; I love the explicit bi rep and the way Sojiro says "Just because you're bi doesn't mean you'll fall in love with anyone willy-nilly." Just, the completely opposite of the "bi people will fall in love with anything that breathes" stereotypes).
