Jo Jung Suk will be making a special cameo in “The Legend of the Blue Sea” to support Jun Ji Hyun, who is a senior in the same agency.

The actor has yet to film his scenes for the drama, though he will be doing so soon.

Also making a cameo is actress Park Jin Joo, who received a ton of love for her role as the utterly unamused nurse in “Don’t Dare to Dream (Jealousy Incarnate),” which starred Jo Jung Suk and Gong Hyo Jin.

These two actors will make their appearances in episode 6 (airing December 1) and episode 7 (airing December 7).
