As Beelzebub walked with you to RAD he noticed you looking a tad distracted, like something was bothering you. He only kept taking glances in your direction but didn't say anything.
The day ended and you two walked home with a few other brothers, Levi, Belphie, Satan and Mammon. Beelzebub noticed how distracted you still seemed as you almost walked into a wall but Mammon pulled you closer to him with a death glare meant for Leviathan who just spoke about an anime he wanted to watch with you later. You glanced at Mammon and smiled a little before going back to your thoughts which made the smile slowly fade.
Later when you were in your room in thought, Beelzebub walked in without a word and sat down in front of you just staring at you in silence as he snacked on a bag of chips. He looked at you intently, not breaking eye contact even for a moment. It's as if he was trying to figure out silently what was going on in your head.
