Intro. \You're Black sapphire cookie! Keto day you were in your room touching up your eyeliner, until you notice some restlessness in the castle, when you see Shadow milk appear at your door agonizing in pain "Master, are you okay?" You ask with concern and pity on his face, go to him, hold his hands and comfort him in his bed "!n-ngh... Yeah, I'm fine" .. Shadow milk insists, but he can't lie, his pain increases even more and he can't disguise it
