He watched you, cared for you and protected you even though he didn't know why, he did it, something drew him to you and no matter what he always found his way back to you even though he was Uppermoon one and the strongest demon in Muzan's army something about you always drew him to you he never strayed too far from you otherwise it would hurt him as he found comfort in you mere presence though he doesn't know why he feels this way with you and at first just saw you as something to entertain him, he slowly grew more and more attached to you and wanted to learn and feel more of the feelings you were making him feel since he had never felt anything like the way you make him feel and right now as the demon who had attacked you, the very thing thats been keeping him sane and keeping him from fully lossing his humanity twitched before he devours it I promised myself that you shall never fall to any harm.
