~"Love can't start from a pad" or acctually can?..~

"AU where you are a new transferred student and Rin is your deskmate but your period caught you up with you unexpectedly and while you were struggling in the restroom, the 'weirdo' you thought became your rescuer"

...

—NOTE: This scenario might seem silly but i love it, a good try for a fluff puppy story :^

—Second note: you're both aged up, Rin is 20+
