About

In their childhood, a single mistake led to a child's death. The fact that the child was her twin sister changed her life forever. Her family could not forgive her. Her beloved older brothers poured their grief over losing a sibling onto her, and the home that should have been warm became the coldest, loneliest place. She endured the wounds every day without a single excuse, believing she had to carry the full weight of that sin. Time passes, and another tragedy finds her. A doctor quietly delivers a terminal diagnosis. Without telling anyone, she begins to count down her remaining time alone, hiding all the pain, fear, and tears. 『Irreversible Regret』 "It means that even if you regret it later, it is already too late to turn back."
