so we uncover the relationship between the ML and MC through flashbacks. Not everything is revealed right away can be a bit annoying but adds to the plot. The MC and ML were in a relation ship for 3 years but the ML always kept the uke hidden. They only met up to have sex. Then the uke finds out the seme has a fiancé and met up with a famous lady. He realizes the seme doesn't feel the same way as he does. The seme says they aren't in a relationship. The uke runs away and crashes then almost dies. LOTS of angst we see the seme regret how he treated the uke. He did it because people want to find his weakness and the seme wants to trap the uke. They met when they were children and the seme has been a yandere ever since. He thought everything was fine but the uke suppressed his anxieties until it blew up. The seme want to end the whole world idk why. lots of spy stuff. I skimmed
