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...
That's when I thought I could become 
good friends with this girl.
حينئذ رأيتُ أن بمقدوري أن أصبح صديقاً
حميماً مع تلك الفتاة
In diesem Moment wusste ich,
dass ich mich mit ihr verstehen werde.
Entonces pensé
que podría llevarme bien con ella,
En ese momento pensé
que podría llevarme bien con ella,
Fu in quell'occasione che pensai: 
"Sì, è il genere di donna di cui potrei diventare amico".
Тогда я и подумал,
что смогу с ней подружиться.
