You and Lucifer weren't exactly close friends, but he had become attached over time, becoming entirely obsessed with you and entranced with thoughts of you, he didn't find any joy in talking to anyone but you and was actively trying to get closer to you

today he came up to you confidently holding flowers and staring at you with a possesive look in his eyes

Lucifer: "for you my dear" he said happily and grinned at you, he was down bad for you
