Reading all the comments about LJS casting and here are my humble opinion. So since his last actin project how many dramas and movies that he been offered or got rumour. Must be around 10 especially the one that been publicizied. He on top right now and cannot fail and must calculate everything if he want to maintain his popularity and become bigger.
Some people think success for actors when he got high rating dramas, box office movies, offered CF/endorsement, pictorial, get highest payment fees. Others may said success when, he can act with his respected senior, acting under esteemed director, doing project for free or with minimal pay because of the causes or what gain his interest. People can gain satisfaction with even small thing that others view as non-important. Project may fail/flop due to various reason and it's a gamble everytime. LJS cannot satisfied his fans expectations.
Acting in a movie is good for him because it offered variety of character from good or evil. Meanwhile dramas only limited him being a goody main lead. Korean movies got many male-eccentric movie from thriller, action, or just drama but why he don't get more offer for movie. If he willing to be second lead in movie or get small screen time, maybe it will give more opportunity for him. Moon Geun Young agency refused movie The Throne at first because she got few screen time but she want to do it because she can act with Song Kang Ho. I know that he in Face Reader movie with SKH and other A-List movie actors.
For drama, I want to see him doing cable. OCN is known with their crime and thriller genre is good start for him. I don't mind him doing KBS drama although some will associate with flop rating as long as the script it good why not and you gain more experience. There one drama Assembly, that I think LJS suit for Taecyeon role. Although there is no love line, the script is really good and that is the first drama that acted by A-list movie actor. You know some movie actor will not doing drama if the script not good.
I wonder if he is friend with actor Lee Joo Seung or An Chan Soo in Pinnochio. The babyface actor is same age as LJS although he not popular but his works are various and crictically acclaim. They should hang out for coffee and sharing tips.
Looking forward for his next project. In the meantime, maybe he will be on the red carpet for Suzy new movie that will premiere end of this year. I remember when he went to VIP Premiere for movie Roaring Current. It must be awesome if he can act with any of the actors in that movie later.
