Boys became men. Actors in their twenties are meeting older actresses and filming the most romantic scenes in their acting careers ever. The actors are at times naïve, and other times direct in expressing their love, shaking the older actresses' hearts. The most popular case would be actor Yoo Ah In of the cable channel JTBC's "Secret Love Affair." Actor Yoo Ah In in the drama plays a genius pianist Lee Sun Jae, and is continuing his romance with actress Kim Hee Ae, who is 19 years older than him. Although the cable channel JTBC's "Secret Love Affair" is a drama about an affair, and the age gap between actor Yoo Ah In and actress Kim Hee Ae is very big, the two are showing off their synergy in the drama.

The second actor in case is actor Suh Kang Joon of the MBC Wednesday Thursday drama "Cunning Single Lady." Actor Suh Kang Joon in the MBC Wednesday Thursday drama "Cunning Single Lady" plays Gook Seung Hyun, who falls in love with the older woman Na Ae Ra, played by actress Lee Min Jung.

Actor Park Suh Joon, who has been loved for his young, fresh aura in dramas such as "I Summon You Gold" and "One Warm Word," is also filming a drama with an older actress in the cable channel tvN's new drama "Witch's Romance."
