La Mosca Manhwa

Kashoo, the incredibly popular confectionery and coffee company, produces the most addicting products. However, there is a mystery behind how the company obtains its raw materials. What lurks on the island from which they obtain their caffeine-laden goods? Just what type of contract are people who are hired to work on this island signing? (To say more about the storyline would take the wind out of the first couple of volume's sails. You really must read it.)
