I think at first, they're high school friends and there's this scene where they play by the beach and light fireworks(?). The seme confesses by saying something like "Do you want to go out with me?" but the uke just plays it off by saying go out for ice cream or something. Then they stop talking. Fast forward and they're coworkers. They walk home together on a rainy and the seme invites himself over to the uke's house for tea, then forces himself on him. There's also a sex scene in the bathroom. Later they meet again at a wedding and I think the uke invites the seme over. He confesses and they eventually get together.

I can actually remember the plot pretty well but the name is escaping me and I can't seem to find it on my computer. I greatly appreciate it if anyone can help!
