After Losing My Memory, I Became a Mom

After a serious illness, An Ya can remember only what happened before she turned eighteen. She even thinks she is eighteen, but when her younger brother, now a head taller than her and far more mature, stands before her, she has no choice but to accept the fact that she has amnesia. Her brother tells her that life after eighteen is no different from how it is now, and that she shouldn't worry about it. An Ya trusts him, and she isn't especially curious about the years she's forgotten anyway. In fact, she's looking forward to the life she has now. She thinks her peaceful, easygoing days will go on forever, but then a four-year-old child appears and shatters that calm. The child even claims to be hers. An Ya, who still remembers being single her whole life, can't believe she could have a child that old. But as the child continues to cling to her, she slowly begins to learn about the memories she has lost.
