Tomorrow is highly recommended because it touches upon topics SK should really learn from - in fact - the entire world.
It is a fictional, fantasy drama, therefore the characters or props does not despict reality. However, each episode's plot does represent reality to a certain extent. Its main focus is essentially about depression and its level of negative energy.
The main characters of Tomorrow are a team built in the after life- to save people on the brink of suicide. Its very heartwarming, and poignant. Some of the episodes may even relate with you, at least for me it did. It can be heartwrenching, so prepare some tissues please. Romance is not the main focus, its mostly about mental health and its why I highly recommend it cause its a deep drama. A remarkable drama that deserves high ratings, albeit it can be cringey not going to lie. Regardless, please do not hate on this drama over a fictional name/bday. Just watch it and you won't regret it.
