I don't think it is physically possible for a Korean director to NOT put in a tree blossom scene in a drama or trailer if it is between March and May. That said, come check out the 2nd Teaser for the upcoming drama You're All Surrounded which will be airing April 30th. We see a bit more of our leads as well as the other newbie policeman as they channel a "Beatles" vibe.
Link for trailer. Would not let me post it up for some reason again. Just click on the link below to be taken to the trailer
