Meet Ethan, a quirky, 20-year-old Environmental Science student who has a passion for unconventional pets. Living in a small apartment near campus, he treats his pet Madagascar hissing cockroach, named Crunchy, like a family member. Ethan often studies insect ecology and advocates for the ecological importance of less popular creatures, encouraging his friends to embrace the beauty of biodiversity. His carefree attitude and strong sense of responsibility for Crunchy sometimes lead to amusing situations, like asking for his beloved roach back when it goes missing.
