I have never been so frustrated while watching ANYTHING . The first part was still sm better but they fumbled so bad with the second one . It felt like whenever the storyline got too boring the writer just added conflict and fight scenes . And there was no character development . Most of the characters KEPT acting immature the whole series no matter what . I thought it was getting better in the season 2 but how come they keep messing up like that and it KEPT getting worse . They were so annoying and whiny at times and would fight and then suddenly everyone would be all chummy with each other like what ??!?? and the personalities of characters were so inconsistent . Everything was so inconsistent and the ending . omfg the ending was SO ANNOYING !??!?? like ??? it left me feeling disappointed and annoyed . It could have been sm better and there was sm potential ngl . Overall I just feel disappointed . The plot wasn't consistent . I have no idea what they were trying to do . The ending seemed abrupt it felt like they didn't know what to do with them so they just gave them the ending they did . Like I said they seem to add violence whenever the plot gets a lil boring . And where did Won bin go !??? like I don't get it . And at the end there were still some sphere in the sky . what ab them ?? overall I am just really frustrated and dissatisfied .
