KSS had a supernatural storyline WWSK does not and plot wise I preferred KSS. I think there is a lot of similarity in the relationship between the main leads and their past.
- FL works for the ML, in WWSK she is his secretary in KSS she is his subordinate and he is her mentor.
- FL and ML knew each other when they were younger and shared a tragedy, in KSS the leads actually knew each other, they grew up together for a bit and were really close, in WWSK they knew each other for like a day.
- FL promises the ML that they will meet again after they part for years (in WWSK she says she will marry him).
- ML finds FL at his workplace were she is his subordinate and he basically makes her life hell with all the work he gives her whilst she does not recognise that he was her childhood friend.
- Takes them several years working together for them to actually develop romantic feelings for each (though in KSS the ML says that he always liked her and in WWKS it is hinted that the ML may have always liked her) other and get together.

This drama is a love story between Kataoka Sakuya, a grim reaper who comes to the human world for the first time, and Mochizuki Nayuki, a woman who lost her father at a young age and has devoted her life to raising her only remaining family—her younger brother. As they meet, they gradually come to understand each other, and slowly, they begin to fall in love. However, a fate that will dramatically change their lives awaits them both…
Soma Yui and Torino Naoki were childhood friends, but they met again as adults. Just as he decides to propose to Yui, Naoki suddenly disappears from Yui's sight after being embroiled in a mysterious incident. Naoki continues to wander in this world as a spirit without knowing that he has died. Naoki asks Uozumi Yuzuru, a detective who is the only one able to see Naoki, to convey his feelings to Yui, but Naoki ends up breaking up without properly saying "thank you, goodbye, and I love you" to the person he loves the most.
