"W - Two Worlds" actor Lee Jong-Suk sent a coffee truck to the set of the SBS drama "The Legend of the Blue Sea." It is to cheer on director Jin Hyuk, lead stars Jun Ji-Hyun and Lee Min-Ho.

The truck provided some snacks and a coffee that warmed the tired body of the entire cast and the staff members of the on-going SBS drama, Soompi reported. Along with the coffee truck is an encouraging banner that reads, "I love you Director Jin Hyuk, Jun Ji Hyun and Lee Min Ho; Goodluck to 'The Legend of the Blue Sea'!"

The show's director then thanked the Hallyu star for his warm and thoughtful gesture through social media. It can be recalled that Jong-Suk made his official acting debut while working with the director Jin on SBS' "Prosecutor Princess" in 2010. They also worked together on 2014's "Doctor Stranger" and Anhui TV's "Jade Lover."

Jong-Suk, best known for his performance as Choi Dal-Po/Ki Ha-Myung in SBS' "Pinocchio," will star next in Park Hye-Ryun's upcoming drama "While You Were Sleeping" opposite miss A's Bae Suzy, News Nate reported. He plays a prosecutor who does all that he can to stop the woman's (Suzy) dreams from becoming real.

"While You Were Sleeping" will benefit from the creativity of director Oh Choong Hwan, whose previous projects include this year's hit SBS drama "Doctors" and the 2013-2014 pan-Asia hit "My Love from the Star." SidusHQ will wrap up all of the necessary logistics before the year ends and commence the production in early 2017.

Not much is known about "While You Were Sleeping" aside from the fact that it will be a 100 percent pre-produced drama and was given a Wednesday-Thursday timeslot on SBS. More details about the project will be revealed soon.

While waiting, fans can catch Jong-Suk as the nation's most beloved actor in Lotte Duty-Free's on-going web drama titled "Seven First Kisses." He will join previously announced actors Lee Joon-Gi, Park Hae-Jin, Min-Ho, Ji Chang-Wook, 2PM's Ok Taecyeon and EXO's Kai.
