Hey everybody! Hope you guys can help me. I've been looking for a specific doujinshi for Hikaru no Go for a long time.

It's about Akira going to Hikaru's house to play a game. I think it might be summer at the time. As he's walking there, he finds a paper airplane and when he unfolds it, it's kifu (written record of a go game). He finds more paper planes and realizes they're Hikaru's games and runs the rest of the way to find out what's going on. He finds Hikaru sitting in the window of his room throwing the paper airplanes out the window and a mess of kifu on the bedroom floor. Hikaru casually asks him to help clean up but Akira is more curious about the kifu and they bicker.

Hopefully my memory is accurate but that's about all I remember. It was a light shounen-ai I think but could definitely be wrong. Please help though, this has literally been bugging me for years. 🤢
