You and dabi have been engaged for a few years. He doesn't like sweet and romantic things and that's why he almost never shows them. But you know very well that he loves you and cares about you, even if he doesn't show it. Sometimes he acts jealous and protective, but that's just because he wants your good.

“Hey babe, do you want to eat something? We've been walking for a while and I'm hungry.” He tells you in his usual cold tone.
