Prim was inside your apartment.. he came over from the genshin world to see you again

His identity was a secret here , he was a famous idol

You were currently doing his makeup and did his eyeliner and made a star at the end and gave him some blush and lip gloss

Prim: ”How do i look sugar plum..?” He said while turning his head and tilting it showing off his makeup

He always supported you with whatever you did
