I had put this on my watchlist ever since I heard the news that Wi Hajoon is playing in this drama, and reading the synopsis made me excited. A while after that I completely forgot about it until the posters, teasers, and trailers started to come out. I had completely forgot that K was supposed to be Suyeol's alter and didn't bother coming back to rea the synopsis, already too excited looking at the pre-show contents and speculating on my own, of course to have the theories broken down realizing he's Suyeol's alter. But, it was so much better than my theories, and anything that I could think of, so I wasn't complaining (well, maybe I did because there were a lot of confusing scenes with Suyeol and K but I just concluded that it was what's going on in Suyeol's mind and that's fine by me, and tbh I think the scenes are very cool and I guess were overall a pretty cool concept)

I really enjoyed watching the whole drama. I kept looking forward to my fridays and saturdays because of the drama. Every time the episode ends, it just left me so curious impatient for the next episode. Thinking about it and making theories about what would happen next, what's the backstory of everything, even just thinking about that made me genuinely excited and happy. Seeing Suyeol and K's bickering, their teamwork, seeing their cool fight scenes, their touching, sad backstory made me go through such a roller coaster. And I loved every single moment of it. Sometimes I would rewatch an episode, maybe watch the scenes memorable to me because I couldn't wait for the next. It's that good, at least to me.

It was my fault for just reading the synopsis but not the genre. I got fooled thinking it has comedy in the genre because of how fun the trailers looked. And of course though a lot of scenes were pretty funny, I didn't expect the drama to be so... much darker, deeper, and sadder. A lot of it was just because of the main characters themselves. Wishing for K to stay with Suyeol to the ending of the drama was impossible, but I still did. After promising that he would leave on the condition that Suyeol would help Huigyeom, I got so sad. A few episodes later when K looked at Suyeol proudly after Suyeol had fought Gyesik made me cry. It was nice to see them be nice and soft, but it made me so sad because I was genuinely scared that K would leave. When he left Suyeol who was stabbed, I panicked, thinking what if it was really his last moment in the drama, completely forgetting the fact that he's the second lead in the drama. Throughout the episode whenever Suyeol thought of K, he didn't cry but I did. When K came back to save him, he didn't cry but I definitely did. And his last goodbye definitely made me cry. No matter how many times I watch that episode, that scene, I can't not cry watching that. It could be because I was biased because of Hajoon that I did, but I can't help but think that it's not because it's Hajoon, it's because of K. Throughout the drama just like Suyeol, I got really attached to K. He was mischievous, righteous, and soft hearted, and he did beat Suyeol up in the first episode (a lot) but, him turning out to be Suyeol's protector alter made sense. I had always felt that, as he always comes out whenever Suyeol needs him. Maybe that was the reason I got so attached to K. And because I got attached to him, now I'm really a big fan of Wi Hajoon. He, (of course along with every cast and staff) did so well for this drama and I really hope they know how many people appreciate this drama. If only tvn has year end award shows, i really feel like they would snatch a couple of categories awards, since thats how good it is.

Last but not least, the OST. there's only 4, and I absolutely enjoyed them all (well, track 4 didnt really stand out to me that much because it was a slow one, but it was still nice to hear, but it's not my cup of tea), and out of the 4, my favorite would have to be BUMP! Hearing the heavy screams in that song genuinely shocked me, but it was also one of the reasons it's my favorite. Well, I don't think I'm a big kdrama fan, as I usually just watch the ones with my favorite actors, and I definitely rarely look up OSTs, a lot of times because I wasn't interested enough. But that song was genuinely amazing. It's definitely one of my favorite genres that I hear a lot from my favorite western bands, so hearing it in a kdrama OST was a little shocking but it made me happy and excited. I wish to hear more OSTs with that type of heavy band sound, surely in an amazing action drama (Would be nice if my favorite actors play in another good action drama like this)
