intro: U-PRINCE is a series of 12 series, each having 4 * 1 hour episodes, and features one young man's journey in finding love in his life.. it's set in the environment of university, and to some extent all the stories are connected, since all young men are making an appearance in other's stories as side characters.
That said, you don't really have to follow the "order of appearance", but, for those who like to keep things chronological, this it the order:
Part 1 : Handsome Cowboy
Part 2 : Gentle Vet
Part 3 : Lovely Geologist
Part 4 : Bad-ass Baker
Part 5 : Absolute Economist
Part 6 : Foxy Pilot
Part 7 : Playful Comm-Arts
Part 8 : Extroverted Humanist
Part 9 : Single Lawyer
Part 10 : Crazy Artist
Part 11 : Badly Politics
Part 12 : Ambitious Boss
Generally, these are ALL cute stories, made to make you smile.

..as for this part:
I have taken this series without giving it much thought. I went into it as "anything goes".. oh, and it went! The Show took me to a nice adventure, with good pace, just the right amount of couple's interaction.
(but, you can read that anywhere)
Shortly: it's a tale of misunderstanding and not being ready to trust the other side; rather trusting the echoes of gossips from those around. This one teaches us, that, if people leave our lives.. we need to let other people come in our lives and stop the rain in our hearts. Also, it teaches us that love does not come in a shape & form we might expect, but more like: it's love that makes us stop caring about messy hair or over-use of disinfectant. :)
I find our OTP strangely paired-up, and yet somehow matching each-other.
The "fear of rain" as the synopsis states is not exactly that, it's more of a trigger for some unpleasant memories that usually results in uncontrollably tearing-up no matter where she is.
Also, I got to say: you GO Show, for showing us girls that attend engineering department, and are capable of taking a course on robotics. Yes, yes.. and playing football with friends, More of that, please; until it spreads all over, and people realize that is's OK to do whatever you like, no matter the "gender role".
Thumb up to this part, for showing diversity in a good light.
What I specifically noticed here is the delicate touch it gave the "third gender", introducing a character of one delightful aunt, a caring, understanding and a bit teasing person, who brought light to world of adults. These are the characters I like seeing poping up in this Show.
The Show also touches the subject of stalking.. but, literally just TOUCHES it, since we never really got to see much of it, and it remained in the cloud of mystery, ending in a quite anti-climatic way.
Also, aside from our OTP, there is another couple, quite unconventional, even for a Thai series, and without spoiling anything I'll put it in just two letters: GL. But, it's a side story, so don't expect much, ok?

Most memorable sentence:
"LOVE HAS NO GENDER".
Mind blowing.. wait, now I need to give this one a 9,00. :)
