Third Boy's A Charm (Grian X Reader)

Cover by @LoveGhosty. Thank you!
Starts the day after the 'Jerry Incident' ended (episode 60), but they don't go house hunting and the Yakuza doesn't chase them and whatever.

You are the new girl at Akedemi High School. You meet Sam, Taurtis...and Grian. You instantly take a liking to the Brit, and he takes a liking to you.
Like in all stories, you get together.
But not all is well. All people have at least one secret.
And yours just happens to be a dark one.
