First of all, Ah....The Visuals...I'm Screaming!!!

I binge watched the entire series. So I would like to disagree with the people who said in the comments that stated there is no development in the relationship between the leads. According to me, the relationship already started developing when "Jun & Jun"(how funny) first met. Maybe they watched it episode by episode which felt like eternity to few people but to me the relationship development went exactly how it is supposed to be.

And again the story is nothing new, just childhood sweethearts becoming a couple but what made it unique is the cameos (Mr. Heart couple and Yim and Tutor), idol to company worker plot and three people aiming(liking) at Lee Jun LOL. Coming to the acting Choi Jun(the actor) definitely delivered what needs to be and also he is sooo handsome, and Lee Jun(the actor) tried his best to act cute when required but fierce character(towards Choi jun) is what made his acting stand out. And the supporting actors also did a good(may be not great) job. Kudos to them. Also, the leads have great chemistry, although it is only shown at the last episodes - definitely worth waiting.....hehehehe :)

But the reason I gave it an 8 instead of 9 or 9.5 is that the story can be a lot more improvised. Also, I felt like few scenes were forcefully made short or few scenes were rather incomplete. Also, the ending scene did not feel like an ending scene at all. But the climax scene is one the greatest climax scenes I've ever watched.

So, watch it for the visuals, watch it for the cameos, watch it for the effort the team has put into, watch it for the great chemistry b/w the leads. Whatever the reason is...Go Watch it!!...A definite one time watch.

P.S. - Not time consuming, Short and sweet, yeah few flaws, but worth the time!!!
