With Beef’s explosive and violent finale, series creator Lee Sung Jin wanted to finish the first season with a sense of resolution. That said, he definitely has ideas for continuing Danny (Steven Yeun) and Amy’s (Ali Wong) story of malaise in America.
“I wanted it to have a conclusive feel just in case,” Lee tells Rolling Stone, “but there are a lot of ideas on my end to keep this story going. I think should we be blessed with a season two, there’s a lot of ways for Danny and Amy to continue. I have one really big general idea that I can’t really say yet, but I have three seasons mapped out in my head currently.”
