First off, I didn't watch the original Japanese version so I'm not going to compare the two. Here's my review =)

STORY
At first, this drama was full of mysteries and you just couldn't wait for the story to unfold, but once they were fully revealed, the excitement dies down quickly. After the mysteries were unfolded, the writers should've then started to develop the romance more but that didn't happen, unfortunately. I guess I was expecting for this drama to be made up of at least 50% romance because, well, the genre IS romance & comedy. But it was more like 15% romance lol. The romance between the leads was very subtle and slow - as in, it doesn't develop until much, MUCH later on, so that was quite disappointing. It disappoints me even more that the main lead and supporting character had more intimate (but dull & unromantic) scenes together than the lead couple. Suho and Ha Yeon Soo actually look very cute together. They have chemistry and there was so much potential for this on-screen couple but the story was just really lacking romance. I guess it focused more on Lee Yoo Chan's past and his journey being a CEO at his own company. I also wished Bora had more character development or stories behind her character because she's one of the leads, but it seemed as if the writers began to neglect her character a little bit later on. She sometimes felt more like a side character.

Some episodes were completely dull. There were sooooo much fillers. The amount of time they spent on Min Tae Ra and the artist she admired was ridiculous. Although, I did find the NEXT IN employees and Bora's friend, Miso, and Cha Do Jin more entertaining than the main story sometimes, just because the episodes would get really dull and those small characters made it a little more interesting and bearable to watch.

ACTING/CAST
I wasn't too pleased with Suho's acting here. I love Suho as a singer, but as an actor... not so much. I don't know what happened to him here. His facial expressions seem really unnatural and awkward sometimes. Is he really lacking acting skills or is it just because he didn't really fit the role of Lee Yoo Chan? Or maybe his character was just poorly written?... I was kind of able to empathize with Yoo Chan because of what he had been through but he was still pretty unlikable most of the time. They should've made him a little bit more likable, at least. Not gonna lie but... if it wasn't for Suho's charming face, his character would've been way more unlikable for me lol I just couldn't seem to hate his character because he looks so angelic haha.

MUSIC
On a positive note... I really liked the OST. The songs are very calming and catchy. A lot of times, I found myself listening to Hard for Me by Cheeze and also Do Young's ver. of that song. Also, Kei's Let's Pray was a really cute song too.

OVERALL
This drama had a lot of potential but it just didn't work out for me, unfortunately. I'd say it was poorly written. I kept hoping it would get better later on because the whole concept of the show is actually interesting, but it didn't get any better. I honestly just continued to watch it just for the sake of finishing it. At least the ending was somewhat satisfying, though.

Would I recommend it? No. Save 16+ hours of your time and watch something better. But if Suho's your bias and you feel that you just really gotta watch it, then go for it lol.
