What is happening?

Right now I'm just really confused. I feel like I have no idea where the story is going to go. I cant really understand what Kyon is thinking at all which is weird since he's the main character and everything has been from his perspective so far. Why is he sick? Is he faking it? Why did he try to kill himself? How come no one is talking about his suicide attempt anymore? How much time has passed since the attack? Why won't Kyon just tell Lucaon what's going on? Is Lucaon really just going to give up on making the cure? How did Lucaon go from being a dick to Kyon to being willing to do anything for him so quickly? Why was Kyon sent there as a sleeper agent? Why is Ryan more focused on being mean to Kyon than trying to find out who sent him and what exactly he has been brainwashed to do?

The art in this story is beautiful and the romance in this chapter was so nice to see after so much difficulty in their relationship, but wtf I don't get what's going on.
