So i have watched this from bugging to end watched many reactions and also rewatched it as well. And finally give you my honest, unfiltered opinion.

1) Is the show good?

+) Yes and no. why? The show started with amazing plot but at the end of the series it left me on a huge disappointment. The show was good and it some ep's it was getting better and in some ep's it was getting worse. I couldn't even bare the last ep,vthats how bad the ending was. The ending of the series was not build apon at all. Im fine with an a open ending and they could have just ended it but nooo, they must drag on. The open ending was not structured properly, it wasn't strong, It didn't have a back-bone. ( One good open ending that was very very build and had an actual back bone was The ending in "P.S I Hate You" that Wanwan's open ending made so much sense and it was so beautiful. The dff open ending makes on sense.)

2) Is the acting/Characters

Acting was very very good specially the actor who plays 'Tee' and the actor who plays 'Fluke'. Fluke was played beautifully. Tee made me cry so hard.
Acting was amazing.

3) Is the producting good?.

+) Yes but something its pure garbage. Like cutting of someone's head with just a string. That's not possible at all. That makes no sense at all.

+) There is a character that makes no sense. They say "They dont want to be a murderer" and they literally kills someone . They say they don't want to be a murderer when they just murdered someone. (This shit was 180 and it makes absolute no sense at all. Im not even joking they say they dont want to murder and legit kills someone the same day. wtf?)

4) How is the romance.

The romance was beautiful and got me shipping ans invested in there love love. Kina sad we didn't get much romace between white and tee (Not a spoiler. they are together from the start).
They where the most pure, healthiest relationship of the series who where so cute together, and which was very wholesome. But the ending ruined it all. They fucked up there relationship and left me with the most bitter tast i filt ever in my whole life. When i mean the fucked it there relationship, I mean it. They fucked up there relationship so bad u couldn't keep watching and just skipped, yup it was so unbearable.
