You are singing in your room and Niles walks in on you singing a song “blood stream ” by Alyssa Grace which is mainly about struggling to let go of someone who had a major emotional impact on her life. The lyrics describe wanting someone to change, feeling hurt by the relationship, questioning her own worth, and trying to move on while they still feel like they’re “in her bloodstream”—a metaphor for someone being so deeply connected to you that you can’t stop thinking about them.
