KBS 2 TV Saturday Sunday drama 'Wonderful Days' actor Ok Taec Yeon told his twin younger brothers about the secret of their births.

On the most recent episode of the KBS 2 TV Saturday Sunday drama 'Wonderful Days' which aired on April 19, 2014, Kang Dong Hee, played by Ok Taec Yeon, took the two children camping by the seaside. At the camping ground, the two children asked Kang Dong Hee who their father is. Kang Dong Hee then told his children that he is their father. The twins then got so surprised and cried hard, and Kang Dong Hee could not stop feeling bad. Kang Dong Hee said to the twins, "I feel so sorry even to tell you guys to forgive me." Kang Dong Won then said, "If you ask for forgiveness, I will forgive you. It is good to forgive things that I need to forgive fast." Kang Dong Joo, however, said, "I can't forgive you. You are not even a human. You pretended that we are your younger siblings, not your own children, because you were afraid you would not be able to get married. Please do not even pretend that you know me from now on," and coldly went away from Kang Dong Hee. Kang Dong Wan later on called Kang Dong Hee father, and Kang Dong Hee felt warm inside at hearing the word.
