Context for some of the tags:
The artist titled this work "小兔子乖乖" (Good Little Bunny), which is the name of a Chinese nursery rhyme that teaches children not to let strangers into their home.

The nursery rhyme is about a little bunny left home alone while its mother runs errands. The mother warns the bunny not to open the door for anyone until she returns. A wolf, knowing the bunny is alone, attempts to trick its way inside to eat it by impersonating the mother rabbit.

Given the context and the visual details, there's some dark storytelling going on. The front door has been left open to the night, allowing fireflies into the home. Among the clothes strewn about is a yellow shirt featuring a bunny print on it, reinforcing the nursery rhyme's symbolism. You can also see three footprints: a shoe print, a bare human footprint, and a large paw print. Considering the artist used the interspecies mating tag on pixiv and there's mystery goop everywhere, it appears the intruder arrived as a human, removed their clothes, transformed into a werewolf, and..."ate" the "bunny" Creepy stuff.
