hi... honestly that fic was written so so long ago when ppl didn't even care about bottom chn as much 😭 I wrote it mainly out of pettiness as we barely had bottom chn mnchn fics and I didn't know how to tag fics. anyways unplanned falling is basically just chn getting railed by mnho on every surface in every position so I didn't see the need to include switch because within the 100k of chn getting fucked, the bottom mnho part was only for few lines plus it was essential to the plot (trust me i didn't even want to write it but my friends told me to include that as it showed how mnho was finally letting go and trusting chn)
so yeahh, I didn't tag switch because in my mind chn is bottom and he kept bottoming and he is going to keep bottoming for mnho 😭 but I have added a tag now. apologies if it made anyone feel uncomfy!
