It's a seme x seme story wherein both are coworkers working as an editor. They are aware that they have very similar taste in a guy and they made an agreement to never make any moves with their authors. One day they found each other attractive but they are torn about who's topping who so they competed on who's cuter and fitted to be a bottom. For more details, I remember the black haired megane ended up being the seme and the light haired guy is the uke.
Here you go, Chapter 3
