1st story: a guy working in a hotel for non-humans. the king of the other world is visiting the hotel...but oddly, the king looks like his childhood friend who went missing after jumping in the lake and got eaten. twist: king is childhood friend who jumped into the lake as a sacrafice in place of the seme. the longer they stay in the other world, they soon forget about theirself in the human world. sseme chases uke to the other world. he write a letter to the hotel so that in the future, both of them not forget about their memories at the hotel.
second: childhood friends who like the sky. one has a fear of height..due to an accident and one gets injured, they stopped hanging out with each other. in high school, seme rapes/forces himself to uke..they both actually like each other though. years later, they see each other in the airplane.
