need help finding a bl

its a supernatural historical bl. from what i remember, the mc was the prince and the queen wanted to stop him from becoming the next king. hes tormented by ghosts at night. the ml was a demon who turns into a dog during the day as punishment for interfering with human life. in order to end his punishment, he has to make a human care about him (i think), and he chose the prince as his target. theres more plot stuff i remember but i think those are probably the most important parts.
