Boys Before Flowers from F4 and Gu Hye-sun premieres on April 12

Boys Before Flowers may be over in Korea, but it's still got its overseas markets in which to promote itself.

Gu Hye-sun and F4 guys Lee Min-ho, Kim Hyun-joong, Kim Bum, and Kim Joon are headed to Japan; they'll arrive in Tokyo on April 15 to make a live television appearance, then hold an event to greet the press and meet fans in person.

The official cast fanmeeting will occur on April 16 in Tokyo Dome City at JCB Hall, at which the two kpop groups SS501 and T-Max will be present to give a special live performance of their songs from the drama soundtrack with actor-bandmates Kim Hyun-joong and Kim Joon.

Boys Before Flowers premieres on Japanese television on April 12, on the Korean specialty channel Mnet. Following that Mnet run, TBS will broadcast the drama on national broadcast television beginning in July.
