Yellow is my favourite guyXguy manga series because it breaks the mould by having two strong male characters, and shuns all of the tropes so endemic to the yaoi and BL genres. Yaoi and BL are generally written for female readers, meaning the main character is usually submissive, and there is a concerning rapey trend of non-con or dub-con content. One guy is always super effeminate and gentle, and one is always hyper masculine and way too pushy. You won't find any of those things in Yellow, and that's what I love about it so much. Beyond that, the series has an actual strong storyline separateto the romance, with a lot of action that you don't normally find in yaoi or BL either. It's two dudes kicking-arse, taking names, and building steamy tension in between. I love everything about it, and I wish more authors would write stories like this. <3
