Beelzebub-jou no Okinimesu mama.

Synopsis

Beelzebub tries to finish her work quickly to impress Mullin, but Mullin mistakenly believes she has done no work and threatens to take a job in the library with Dantalion. Beelzebub tells Belphegor about the time she almost kissed Mullin and wonders if Mullin hates her. Mullin assures Beelzebub he would never take the job. Beelzebub apologizes for being difficult. The narrator point out this is their first lovers quarrel, though neither is aware of it. Belphegor has an embarrassing dream of confessing her love to Azazel. Azazel saves her from some falling books so she tries to say "I like you" but accidentally says "Memorandum" then flees to the bathroom. Mullin falls asleep and Beelzebub hears him dreaming about her. Azazel falls asleep so Adrammelech ties flowers into his ponytail. Sargatanas falls asleep so Astaroth escapes from the office. Belphegor falls asleep so Azazel carefully puts a blanket on her so she won't wake up and become scared. Dantalion is awoken by Molech which angers Eurynome who had been watching him sleep. Beelzebub falls asleep and Mullin panics at what to do with her. He settles for moving her hair out of her face then panics when he is caught by one of his secretaries. Beelzebub becomes embarrassed herself as she had woken up halfway through Mullin's panicking but been too embarrassed to open her eyes.
