This is a 2017 South Korean drama with 16, 70 minute episodes

Han Se-joo / Seo Hwi-young (Yoo Ah-In) is a famous author who hits a slump shortly after he meets one of his top fans, Jeon Seol / Ryu Soo-hyun / Anastacia (Im Soo Jung) Jin Seol was an Olympic level shooter who lost her desire to pursue the sport when holding the gun would bring on flashes of disturbing memories. Jin Seol is thrilled when her delivery service leads her to drop off a package at none other than Se-joo’s house. However, Se-Joo is not a fan of people in general and particularly this fan who finds excuses to seek him out. The package contains a typewriter that Se-Joo admired in an antique shop but was told it was not for sale. Seems the owner had a change of heart. The typewriter is not just any typewriter but holds a secret that ties Se-joo, Jin-Seol and a third character associated with the typewriter, Jin-oh / Shin Yool (Go Kyung-pyo) together. Collaborating on a novel about their past may break Se-joo out of his slump, allow Jin Seol an excuse to be around Se-Joo and reveal how and why the three are drawn to each other.

Spoiler 🚨. I liked everything about this. The reincarnation angle was interesting and the back story with the ghost was compelling. It was clear that their past story would be sad so it did not fall too heavy when the sad part occurred because it was expected. It kept you guessing just enough to make you want to keep watching. The love stories were believable and relatable. The friendships were heart warming. Getting a slice of life of that era in Korea was interesting.. The only thing that detracted and kept the ending from feeling thoroughly happy was not knowing what the future held for the ghost. It is a thoroughly engaging story with great character development, an intriguing premise and interesting plot. I highly recommend this for a wide audience but those interested in modern history, that like mystery, action, supernatural elements and romance will particularly enjoy this one.
