If anyone's read to the end, does it end with a tragedy? I accidently saw some comments that make me think that Kyon will leave Lucaon. (Noooo?!?!-) I'd like to know if this is going to end sadly/bittersweetly or if the ending is open for interpretation or smth. I've followed this series for a long time before forgetting about it momentarily, so ima be real salty if it ends on a sad/tragic note (╯°Д °)╯╧╧
