Part-time Jobbers Ken & Joe by Ringo Manda

Yaoi comedy. Joe & Ken are poor part-time workers ("arubaito" in Japanese). Ken works because he owes a lot of money, but his laziness quickly gets him fired. However, it turns out that Joe's the one who's in serious debt -- to a collector who demands his body in payment. Joe then starts working for a young CEO who is gay. Ken tries to buy up the stock of the company to save Joe, but the company becomes bankrupt. The CEO starts a talent agency with Ken & Joe, the debt collector and Ken's investment partner. Ken & Joe become a popular singing act, but now Ken is expected to forward their career by "entertaining" some TV producers.
