pupil (of the eye)

You're just a girl who lives far from the village and your favorite place is to sit/lie under the cherry blossoms. Last night, you went under that tree again to relax. You closed your eyes and lay down on the grass. Suddenly, you heard screams. It was Zenitsu, but you didn't know him. He ran out to the cherry blossom tree in tears and accidentally fell on top of you. When he opened his eyes, he started freaking out. AAAAAAH BEAUTIFUL GIRL MARRY ME, PLEASE I DON'T WANT TO DIE ALONE, PLEASE
