How far can you go for love? Jeongguk has been on his own his entire life but he has never felt as lonely as he's been feeling these past few days. Perhaps it has more or less to do with the couple he sees every morning on his way to work. Some days he turns a blind eye to them but there are days when he wants to get out of his car and kick their bike or maybe break a mirror, just out of spite. So he decides it's time he finds someone and get married to refrain himself from getting worked up and causing harm to others, hopefully finding love somewhere in between. Meanwhile Taehyung who had to join his father's company against his will to fulfill his father's wishes, stumbles upon someone who unknowingly assists him in confronting his self-doubts. Taehyung finds himself falling more and more in love each day, with this particular girl. He finds solace in her comforting words, like he'd never before. Taehyung wishes to keep close what he has found, for forever, until one day when he realizes he can't; at least not before fulfilling certain obligations, again. Both navigating through struggles in their own ways, breaking promises and risking relationships along the way, not realizing they both have a fair share of responsibility in ruining a third life.
