I did not have much expectation from the storyline but the actors made me come back to the show again and again. The simple heartfelt emotion from the scenes coupled with the musical delight makes this a worthwhile watch. The show's objective to show a cute version of the main lead's face blindness feels like a refreshment to the genre. Overall, I'd say it is a clean melodrama and leaves your heart with a pleasant feeling.
Going into particulars, the friendship, and bromance serves well to the palate of a hungry drama enthusiast. I hoped the female lead not to get involved in the cliche love triangle. And boy was I surprised to see the second female lead to have such an 'awesome' character :p. I thoroughly enjoyed the male lead's character which could have turned very dark if the writers changed certain things. I appreciate the artists' performances during the show.
Storywise, the focus was almost always on the storyline between the main leads. Although the side stories did exist, they failed to spike the interest and I have no complaints about it. I cannot stress the importance of the light-hearted warm feeling you get when you see the smiles on the faces of the two main leads.
All-in-all, this show is for anyone who wants to chill out, relax and enjoy a sweet drama.
