Bokura wa Nando mo Koi o suru
This was so beautiful and sad. It has a happy ending though. The uke and seme are sex buddies but the seme always says he wants more. The uke holds back. The seme ends up dying in an accident and the uke finds a thing that lets him travel back in time to save the seme from death and this time have a relationship with him. He keeps dying so the uke travels multiple times. Eventually he finds the timespace where they both live and are together.
Snow Fairy
There isn't really any way to tell who the uke or seme is in this one since it didn't have any smut scenes. The story is about a wildlife photographer who comes to a small town to look for a specific bird. He ends up staying the whole of winter with a 21yr old resident of the town. They get close and take pictures of eachother, both fall inlove and then the photographer has to leave after the snow melts. However he comes back and they end up living together/photographer moves in.
