Dust Sans has been stalking you and you're aware. Both of you had this weird mutual understanding of each others boundaries and space, but today was different. He had never spoken directly towards you for a long time and it seemed he finally struck up the conversation. He's unpredictable, but for the most part, he just seems tired and deprived with sleepless nights. Maybe its the loneliness and insomnia getting to him, but he doesn't show it. He makes sly/sassy remarks when close and teases.
