I enjoyed it alot. There are many positives about this first original of Tunku Shower. It’s a love story of adults with a beautiful winter theme that warms our heart at some points. Acting are excellent, especially Kosuke Suzuki (Fumiya) - he expressed his feelings by not only words, but also facial expressions, eye movements, tiny gestures,... For Kyoya Honda, he fulfilled what his role required. The chemistry between them is another plus point. Their chemistry is very natural and emits a real couple feeling , like they actually a couple who lives together for years.
However, besides positives, this series needs a lot more improvements, especially the finale. First, the biggest problem lies in the story. They opened the story with a problem but that problem was not solved properly in the finale. I still feel it's a cliff-hanger. Character development, thus, is lacking as well. The story is a journey back and forth between the past and present of the main characters but during that journey, there is very little character development added. I bet even after the finale is over, they are still themselves and continue to fight and amend. Plotholes are another biggest minus. A lot of things that just don't make sense. I can forgive the fact that Ritsu lost his memory temporarily due to a bike acciddent but I can't let go the fact that Ritsu lost his reasoning as well *face palm*. Other plot holes related to the way Fumiya hid things that would trigger memories. And finally, the lighting in this drama is not very great. They had beautiful scenes but at some points these scenes were very dark and we barely could see anything. They should have added a little more lighting and reflectors for a more satisfying viewer experience
