Part A
The sweater that Beelzebub had gotten from Mullin that she liked so much starts to come undone. Beelzebub is in so much shock that she keeps sighing and trying to avoid eye contact with Mullin. Mullin misunderstands and feels like he made her upset again somehow...
Part B
Beelzebub have a flower viewing party now that spring is here. Beelzebub says that she’s never being to a flower viewing party, so the others go all out for her. Since the day is so chill, Mullin happens to remember when he first became Beelzebub’s attendant...
Yeah, it's the season where you have 
to fend of being sleepy all the time.
نعم، إنه الموسم حيث يتوجب عليك مقاومة
النعاس طوال الوقت
Ja, in dieser Jahreszeit muss man
ständig gegen die Müdigkeit ankämpfen.
En esta estación
sientes sueño todo el tiempo.
En esta estación
uno tiene sueño todo el tiempo.
La saison
où on a tendance à s’assoupir.
Appunto, la stagione in cui bisogna lottare 
contro quella continua sonnolenza.
Realmente, é a época do ano
para lutar contra a sonolência.
Да, пора, когда
всё время клонит в сон.
