Sung Joon is expected to play the male lead in the 16-episode Korean romantic comedy drama "Mojito" which is being produced in advance. He has received a proposal for the role and is still under discussion. Sung Joon has received the role of Choi Ji-woo, the 28-year-old owner of a cocktail cafe that is only open during the day, and the female lead is Su Jong-hee, a 26-year-old nightclub kitchen helper. This drama tells a lighthearted romantic comedy story about an heir who becomes uneasy at night and only runs a bar during the day. He meets a woman who has insufficient balance in his life, and then the two overcome their pain and fall in love. It is expected to be broadcast in the summer or the second half of the year. The broadcasting station has not been determined. It is possible that the three major stations and cable stations will broadcast it. Currently, other roles outside the male lead are also being cast.
