Lee donned a black and white houndstooth jacket and adopted a gray-suited look, appealing to audiences as a polished "flower boy."

Minoz Mansion marked the first time domestic audiences had the opportunity to attend a concert event featuring "The Heirs" actor since 2014.

The concert follows his 2015 mini album release, "The Day," a musical compilation dedication to his fans. Lee will perform in Japan on January 25 in a follow-up to his Seoul-based event.

Minoz Mansion precedes the release of his highly anticipated Korean-Chinese co-production film, "Bounty Hunters," which marks the second major silver screen role for the actor, who is widely recognized for his dramatic appearances in roles ranging from "Boys Over Flowers" and "City Hunter" to "The Heirs."
