"Even if I’ve lost my memory… Jin Kyudo again? This really is one persistent bond…" Jin Kyudo, determined to start a new life, reunites on his first day at a new job with Shin Danbi, a once significant and unforgettable ex-girlfriend. Unlike Kyudo, who is confused and unsettled, Danbi remains calm—almost unbelievably so. The reason: due to an accident, she has completely forgotten her past with Kyudo. Afraid of hurting her a second time, Kyudo tries to keep his distance. Yet Danbi finds herself inexplicably drawn to the warm and familiar feeling this stranger evokes. A tangled romance, like a knotted thread: Kyudo, who wants to sever the tie, Danbi, who can’t let go, and Choi Anh, who slowly wedges his way between them. In the empty space left by lost memories, new emotions begin to gently soak into the soul.
