Subaru Sakamaki one shot SubaruxReader

(Y/n) (L/n), a girl who has suffered from a past of nothing but tragedy and little hope for a brighter future, followed a dear friend to a school held for certain students who keep the country of Japan safe from an unseen foe. Demons. But little does she know that as she attends the cram school of the famous True Cross Academy, she is in the presence of a demon who withholds the flames of Satan within. A klutz who can't stay awake for one whole class period or get over a 50% on a test. Little does young (y/n) know that she would soon be tethered to Rin Okumura, the son of the Devil himself.
