This is one of the most unknown, unexpected and under-mentioned dramas.... Although a cdrama reviewer has included this into her top 10 dramas of 2019 (WaWa Mei) and a colleague rec this too, I only watch this now (yr 2021). Was misled by that horrendous trailer that made it look like a slapstick comedy and failed to show this drama is more than comedy... That it has serious fantasy with decent CGI, and humane stories covering a wide range of life topics:-

1) What if you have a dream but your loved ones are against you pursuing this dream? What if you have the means to keep your family happy and pursue your dream?.... Yet after few years, you regret the decision and want to change again...?

2) What if you wish to die but you are an immortal? What can give you the courage to continue living? (parts of the dialogue here, can be applied to depression/suicide too)

3) What if you have the opportunity to do something you loved and dreamt of for years but screwed up when you had the chance? You spent your next years pining over that 1 lost chance.... How to solve your everlasting regret?

4) What if you have a dream but becos of your birth, you might never be able to achieve your dream... Then in a twist of fate, there was an error at your application and everyone thought you are of elite birth and so you got accepted for your dream job?....

5) What if your love is forbidden? Will you keep quiet and sacrifice the love, or take the chance?

6) What is true love? Can true love conquer all? Even if your loved one might change gender at a certain age....

etc, and more!

The other thing I really like about this drama:- there are no cold face, all powerful ML or Marysue FL!! In fact all the main female characters are smart, independent and very clear about their life goals... They have plans and objectives! Instead the ML is quite an aimless, happy-go-lucky man at the start of the drama.... and develop to be more mature and focused as the plot develops.

Excellent acting from the main cast, even a supporting female character (in point 1 listed above) puts in a tremendous performance! Fyi, when the actress sings for her role, that was her real voice too!! Beautiful and can both act and sing, swooning....

So why 0.5 point deduction? Plotholes. Quite a few and 1 mega plothole in the last episode (thanks to the good cinematography, i can turn a blind eye to that glaring plothole)... There are a few "filler episodes" too, which give it a bit of drag in the middle parts.

A really wonderful drama, love the scriptwriting and art direction!
