I totally agree with your review as I felt exactly the same. the whole dra was driven by YZR. The FL,case an actress not great, and character was very annoying, believing everyone else and putting everything else before the ML who time and again continued to prove her his love.
I totally agree with this review. she annoyed me at her lack of self respect. in HK she should've left and him cashing after her trying to make it up to her. also agree that there were big holes after HK. the part o enjoyed the best was the first half (up to high-school). after that, I just kept fast fwd. Couldn't care about the dragging script and fluffy scenes like the whole university period.
I totally agree with all your points. hence that I gave it 8.5 and not a higher Rak. despite all the good. if I can add another thing that annoyed me, was that Jiun was pretty useless aside from his medical skills. what's the point of being a half God if he doesn't use any of his powers? same goes for his mum.
