The story, without the spoilers.
Ban Ji-eum has been reborn again and again, and unlike everyone else, she remembers every life she has lived. In her eighteenth life, she loved a boy named Moon Seo-ha, but she died young and left him grieving. Now, in her nineteenth life, she is determined to find him again and stay close to him — even though he has no idea who she really is. See You in My 19th Life is a gentle, romantic fantasy with a lovely central idea and a warm, confident heroine. Shin Hye-sun is charming as Ji-eum, a woman with centuries of experience inside a young life, and Ahn Bo-hyun is steady and appealing as Seo-ha. The reincarnation premise is used more for romance than for deep world-building, and the villain subplot is weaker than the love story. But if you enjoy a sweet fantasy romance with a heroine who knows exactly what she wants, this is an easy and enjoyable watch.
A little curiosity. A new favourite.
