My insights so far

They're each other's priority, yet both of them aren't honest about how they truly feel. Karel loves Sasya and Sasya loves Karel ITS MUTUAL!. But due to Karel's job as a double agent, he can't just openly love Sasya or be with Sasya just like he always wanted, and he doesn't want to let Sasya know about it since he doesn't want him to worry, so he gotta make sure to get all his job done, so him and Sasya and maybe Charles too can live together peacefully. For Sasya, I think he has PTSD, anxiety disorder, and he's emotionally unstable. Without Karel by his side he gets anxious and tend to think that Karel won't be coming back after his fake marriage. I'm also annoyed with madame Rambouillet or something like hey b!tch stop being delusional ARGHHH I want to pull that little curls of yours seriously

I actually love the story regardless how frustrating this is. I lost count of how many times I paused reading just to prioritize my own mental health and ease my stress and annoyance towards the story HAHAH

If you haven't read til the last chapter, I hope you do, I can see that it's going to be a happy ending, but since it's still ongoing I think they wish to end my life first

I can smell more angst ahead
