"Heirs" Lee Min Ho appeared as a "Lucifer" in the high school of evils.

On the fifth episode of SBS Wednesday Thursday drama, "Heirs," aired on October 23, 2013, Kim Tan came back to the Empire High School in three years, after voluntarily returning from the United States coming back to Korea.

In the morning of his first school day, when Kim Tan appeared in school, students gathered around and talked about him. Lee Hyo Jin (Kang Ha Neul), who had been watching the students on the top floor of the school buidling, said, "Lucifer's return in the school of satans, how interesting."

Kim Tan said hello to students who had come to see him, gathered around his seat. Kim Tan said to Lee Bo Na (Cyrstal) and You Ra Hel (Kim Ji Won), "Long time no see! There's no one who doesn't know that we're engaged, even if you don't stare at me like that."

Choi Young Do (Kim Woo Bin) then made an appearance, pushing away the group of students. Kim Tan said to Choi Young Do, who stared at him coldly, "I missed you, friend?" Young Do replied coldly, "Welcome."
