The mini-series with Suho was nice, which had good approaches, but was still not enough for a better place in my heart. At first I was skeptical about the actress, but in the end she fitted in well with the personality of the protagonist. Still, the acting skills were on a low level, as you could clearly feel the embarrassment between them.
The story hadn't fully unfolded, sure, some approaches were good, but it seems like an unsafe framework. The male protagonist's love for the female also seemed implausible, probably because it happened too quickly. The work as a reaper was depicted a bit contourless, a little more spice would not have hurt.
What I really liked was the friendship between the main character and the stuck ghost in the real world. She is a loyal fangirl who believes in the good of her idol despite his bad behavior.
And of course the touching finale, which touched my heart. The mutual time spent together building a small family and a stronger bond. That she sacrificed her life afterwards for a little girl so that she can experience more than before. She had done this not only for the time with her lover, to spend more time with him, but also for the girl. So she had shown her pure heart until the end.
