Personally, as a fan of the webtoon i was a little dissapointed by this drama. I felt like some of the characters had a completely different personality than in the webtoon and it bothered me quite a lot. The storyline was also? Weird to me, and i dropped it. I'm not sure if it had gotten better in the later episodes would've gotten better, but it unfortunately wasn't my cup of tea and i felt weird watching it.
On the positive side, the actors were well picked! Cha Eunwoo really suited the role of Suho and he even has quite same looks haha! It made me thought if Suho has got inspiration from him LOL.
Original sound track was good too, it brought a nice vibe to the episodes :)
