Cooler Than Me (Semishira)
1 part Complete Semi Eita really hates Shirabu Kenjirou, except he also kind of loves him. Basically a telling of Semi and Shirabu's relationship from when they first met from Semi's side.
Also just a sidenote, they don't get together in this one but there are two more fics part of this series where they do get together, so stay tuned if you're brave enough to read this trash :)
