The Best Cure for a Fear of Needles (Ichimatsu X Naga!Reader)

The day I originally posted this script on Deviantart, I stumbled across this great Tumblr page that has many translated Osomatsu-san fancomics. One of them was about Ichimatsu's fear of needles and how he had to get his vaccine. While I readed it, I had this crazy idea: What would happen if Ichimatsu had a naga girlfriend/boyfriend who puts him in a happy trance so he won't feel the needle? And the result is this little script. In my story, The Matsuno brothers knows that Ichimatsu's significant other is a naga, but they've never actually seen her/him as a naga. That is because you, dear reader, owns a magic pendant that allows you to change into a human and back into a naga whenever you want. Only the Matsuno family knows your true self and they agreed to keep it a secret because they like you. But...As nothing can calm your boyfriend down, you have no choice but to transform into a naga in front of the doctor to keep Ichimatsu from trashing around and help him relax.
