Amazing show. First I wanna say that Yoon Shi Yoon is an amazing actor. He depicted anxiety so well. If you are experiencing anxiety or have in the past, this show really resonates with you and even becomes inspiring. You see the struggles the main characters go through and it is so easily relatable. While I do understand that those who don't really have anxiety would think the slow is kinda slow, that is because they don't understand how hard it is to overcome anxiety. It takes time and effort. It is a really scary thing to overcome. I've watched a lot of kdrama's but this one hit me the most.
