Please help, forgotten title, bl manhwa

Can you guys help me find the title of this story? If I’m not mistaken, it’s about an MC who takes care of an ML who is under a curse. The MC, who is a servant, doesn’t know that the food he gives to the ML is poisoned. When he finds out, he also eats the poison out of guilt, and as a result, the MC ends up with a damaged voice. It’s a BL story set in the Joseon era, I think? I forgot
