Inseparable Bros

Without the body 'Dong-gu' (LEE Kwang-soo), the brain 'Se-ha' (SHIN Ha-kyun) can't go anywhere because he's a paraplegic, and Dong-gu can't do anything without Se-ha taking charge of the situation due to his mental disability. Even though they are not biological brothers, they've lived and helped each other for over 20 years, complimenting what they lack. One day, their assisted living facility 'House of Responsibility' is on the verge of shutting down for good when the pastor who took it upon himself to run it passes away. Without any donations and funding to keep the lights on, the brothers and other disabled people are in a major trouble as all of them are in a danger of getting dispersed to other facilities. In order to keep House of Responsibility running, Se-ha executes a scheme to bring in some money in exchange for giving away volunteer hours to students and anyone looking to pad their resumes. He also gets Mi-hyun, who was recently let go from her part-time job at a local pool, to become Dong-gu's coach so that he could compete at swimming tournaments and win prize money. But the hope of staying together doesn't last long as someone who claims to be Dong-gu's mother comes forward.
