I began watching TUC without any expectations, since at that point I've never heard of it before and it wasn't that popular in my area. However, it became my favorite kdrama of all times and the counters hold now a special place in my heart.

The story was beautifully written with lots of emotion and depth. Each counter has its traumatic past that was amazingly written without making it feel ankward like in many other dramas. The character development was there and their growth was really beautiful to watch.

Acting was done right. We have 4 leads with impressive backgrounds behind : Jo ByeongKyu, Kim Sejeong, Yeom Hyeran and Yoo Junsang. Honorable mentions to Lee HongNae. - played Ji Cheongsin I think it was ByeongKyu's first lead role and he did an exceptional job.

OST : I'd like to recommend Sejeong's OST "Meet Again", an emotional song written by her that will deeply touch your heart.
The rest of the OST was really cool as well.

So yes. TUC is a must watch, deep with many lessons, but also funny that will heal you in the end.
