I agree!!! We all had a very good hint that Zhenya is Psikh and was just waiting for the reveal BUUUUT that reveal was so effing insane! From Ch 34 where things started to heat in teasing Sergei then things turned out to be all gruesome until Ch 37. My heart was crushed for Kwon Taekjoo because he was just starting to open up to Zhenya and yet that happened... I mean...
in the end I felt like I was watching a spy movie.
Thank you Chrysanthemum Garden for a wonderful translation. And to the commented here whom I got the link. I will find you and thank you!
Here's the link if you wanna read it.

RIGHT the way Shenya was making his desire for Taekjoo more explicit to him… I loved reading them fight and conquer their ‘enemy’ together. It’s a shame to see them like this, but this is the angst that comes with spy dramas.
Sometimes, or maybe in the future, I’d like to see Taekjoo get the better of Shenya and dupe him more often.
Thanks for posting the translation link for more others!

I didn’t read it until the end because I couldn’t find a quality English translation that is completed yet but Chrysanthemum Garden does a great job at accurately translating the original novel. Anyhow, they’ve done up to the second arc and SPOILER SPOILER SPOILER SPOILER
The reveal of Shenya as Pshik Bogdanov blew my mind. Taekjoo’s inner monologue as he comprehends Shenya’s facade ached my heart to read. It was great, I wanted to save him myself. However, the very in detail rape after that was not pleasant to read. I’m aware we can click off as soon as we aren’t interested, but it was particularly vulgar and disgusting.
