Suhee, a water purifier management manager, discovers she has urinary incontinence due to an unexpected incident at a customer's house.

“Water purifier!” Suhee’s energetic voice is as confident as her customer’s trust in her as a water purifier technician. And her big smile makes her look warm and big-hearted, which fits a service job. The uncontrollable changes in her body and in her hectic life are flustering and vexing, but it is just another bumpy stepping stone in her life. The bittersweet days with Oksun set cracks in Suhee’s body and soul, and only her warmth remains after a series of commotions. (KANG Jin-ah)
