For me, there are no plot holes at all! Because if viewers would only give the story a thought... the plot is actually rationale, understandable, and justifiable. Having multiple men liking the female lead was kind of common already, such set-up was typical but what makes this drama unique/peculiar are the characters itself.

Because as a Writer it's actually not easy to make difference between the lead characters, given the fact that we actually have three male leads here. And ofcourse the actors gave justice to the roles because they really did great work of portraying three different leads that is totally different from each other. Astro members originally debuted first as actors so I wouldn't say that Rocky and MJ improved, because I have the feeling that they must have been this great already but they unfortunately wasn't given the opportunity to fully show off their skills in their previous actings.

Cold first lead then Caring Second lead is kind of very common already in dramas nowadays so what makes this drama more commendable is the fact that... two of the three male leads are both having unfiltered personality BUT their character are very different from each other.

Because considering MJ's way of confession, maybe his unfiltered character is through words? while considering Rocky's courtship towards the female lead, his unfiltered character is through his actions? Somehow goes like that. But as for Han Gichan, I'm not saying this because I'm not a hardstan fan of him... but I think he was a bit awkward in his acting here, especially because his role was a Manager. And his role wasn't totally coming out, because Managers in general was like you know... Totally Dignified, Smart. But I actually understand it because I know it's hard to play a good-hearted and innocent character.

In conclusion, I commend the actings of Rocky, MJ, and also Lee Taehyung. I mean, who wouldn't? This was fictional but their acting especially Rocky's acting made me wonderif they are still acting. Because Rocky's acting was really smooth to the point that his acting made me think if is this how romantic Rocky will become towards his future girlfriend... I didn't doubted MJ's acting because I already know how much of a crackhead he is, so I think he was no longer acting here LOL.

Lee Taehyung's acting in the other hand, really made me wonder if he also have such disappointing personality in real life. I mean, I'm sorry for thinking bad of him... I can actually feel that he was a nice person but his role here as Changyoon really made me doubt because his acting was just totally great.

Well no need for full OSTs because the background musics alone are capable already of making the audience feel the thrill. Rewatch Value? No words can express how deserving is this drama to be rewatch over again. The ending and conflict resolution is beyond satisfying that it could urge the viewers to watch it again. Because it can be seen in the trailer that the it hiding amongst the female lead's romance must be found, and the culprit was indeed hiding amongst the romance! or should I rather say... he's hiding "behind" the romance? ^^
