«Satan applies sunscreen heavily to keep his skin pale»
«Belphegor lies on a chaise lounge, under an umbrella. With sunglasses and comfort. Beleth arranges a place for him»
Sitri: Oh, you'll burn if you don't wear sunblock. It harms the skin. Here
«Sitri gives him a whole tube»
Beleth: Um.. thanks, but–
Belphegor: Leave him alone. Applying cream all over your body is tiring. He doesn't need it
Sitri: But there's a lot of sun here. He'll be hurt later
Belphegor: I won't repeat it twice...
Sitri: In that case, I'll anoint it myself
«Squeezing out a little, Sitri quickly passes her hand over Beleth's face, but he managed to move away, and Sitri touched his hand»
Beleth: Sitri, No need. I'm fine as is
Sitri: Oh, okay. Sorry, I wanted the best, but I got carried away
«Everyone forgot about it and Belef didn’t wash off his sunscreen»
«That same evening, Baleth in front of the mirror with most of her tanned skin and a small patch of pale skin on her arm, face and neck»
