Tanjirou is new at demon slayer academy while Rengoku cant seem to stop thinking about tanjiro

ɪɴ ᴛʜᴇ ᴘʀᴏᴄᴇss ᴏғ ʀᴇᴡʀɪᴛɪɴɢ... Rengoku Kyojuro had come to the real world! But sadly, you aren't all lovey dovey like what you had expected. Instead, you're filled with heartache and bitter tears as your knees hit the ground with your hand clenching on your shirt after facing the shitty reality. It wasn't what you had expected. You had thought that once your favorite anime character had come to life, you would be the happiest person on earth while you steal kisses from each other. But no, him coming to the real world did not give you delight, but pain, suffering, heartache, and dehydration from the amount of tears you have shed. Helloo, this is my fanfic starring my only ever male crush and you! I got this idea from my multiple mental breakdowns about how he doesn't exist and I wondered, "What if he came to the real world?" but guess what~ bitch hurted even more~ BY THE WAY THIS AWESOME COVER IS BY SANEMI SENPAIIII: @_sapiro_

Both of them are breathless, it means they can't use any breaths like demon slayers and pillars can do. Yumi and Senjuro are breathless and that's their destiny. They promised to help each others back.But what if Senjuro suddenly changed, that he suddenly become a demon slayer and can use breaths anymore. His attitude also changed and it feels like he is in darkness. Can Yumi saved Senjuro without breaths?

Rengoku x reader = his wife to be. This fanfic is mostly fluff and LOTS of Senjuro content <3 (Slight angst turns into heavy angst at the end, so read with caution!)
