I really like the detail that Marcille is the one backing away in panic. Falin isn't grossed out, just surprised (because she can never figure out people are in love with her, this has been established).
I love how surprised Marine looks. It's always fun when fanart has Pekora being the aggressive one. It's pretty out of character, but it feels like it COULD be accurate if she wanted it to be, if that makes any sense.
