After an unsuccessful and traumatizing mission, a skilled demon slayer by the name Tanjiro finds himself unable to perform total concentration breathing. He lives in fear and anxiety due to the intense fighting block he has been burdened with since his last mission. He's far too behind his friends to be of any help, and sadly, the boy receives a short training-break pass for four months. Nothing seem to help his little situation - until he learns of the rude, young Mist Hashira, who supposedly exceeds at training newbies. At first Tanjiro feels a little skeptic; due to the unfriendly aura around the Mist Hashira. But little does Tanjiro know that shortly into his new path - one fraught with uncertainty - he will be trained by the same, rude boy, and he might feel more attracted to him, than he thinks. ___________ Please note that both characters are in my story aged up! This story contains smut in later chapters, so watch out for that. This is a remastered version of my old fic, called 'Our Deal' Top Tanjiro, Teasing Bottom Mui! Enjoy!
