Director Reveals Story Behind Rowoon's Unexpected Appearance in 'A Time Called You'

Rowoon's appearance in "A Time Called You" may be short, but indeed made an impression. He played the role of Tae Ha, Koo Yeon Jun's best friend and love interest in the series.

In an interview, the drama's director Kim Jin Won revealed the reason for casting the idol-actor.

According to Kim PD'nim, he put a lot of thought into making the scene work. For him, the intended chemistry would only come out if Ahn Hyo Seop, who played Yeon Jun, should be portrayed by an actor with whom he is comfortable interacting emotionally.

Little did many know, that Ahn Hyo Seop and Rowoon are actually close friends in real life. Director Kim then asked the "Business Proposal" star who is the actor he is close with and at that time a sad story immediately came up on the spot.
