Negative emotions will condense into physical creatures, such as "anxiety is a hedgehog" and "depression is gray fog." There are people who specialize in recycling these emo entities, and the recycling methods are all kinds of weird - such as using "childhood toys" to lure away the loneliness of adults. The trashy heroine accidentally became an emo recycler. While helping others clean up their emotional garbage, she discovered that the senior she had a crush on had an "ex memory octopus" living in her heart that refused to leave.
