A Star Brighter Than the Sun tells the first love story of Sae Iwata, a girl who is slightly stronger than average. While still in elementary school, Sakue fell in love at first sight with the smile of her classmate, Kamisihiro Mitsuteru. Kamishiro was small and skinny back then, but by the time they reached middle school, he had grown into a very handsome man, and Sakue became a distant figure. However, when they meet again at their last sports festival in middle school, the love that was buried deep inside Sakue’s heart begins to grow.***
