I am a great fan of Lee Min Ho. Not only is he a korean singer but he is also a very good actor !
He has played in many films and series such as City Hunter, Boys Over Flowers and on and on.
He began his career when he was 18 years old. I appreciate his performance.
To my mind, he is the best korean actor.

"And on and on" : "et ainsi de suite"
"Such as" signifie "tel que". Ici: (séries) telles que
