A chance encounter brought someone from a parallel world to this one through transmigration. Since we met, it must be fate. No matter how far away you hide, even at the ends of the earth, I will find you. Even if I become a speck of dust, you will still shine in my heart like a little sun.
Note: One female lead, with Yukino as the pairing. There are love-triangle clashes in the early and middle parts, since nobody really understands their own feelings yet. The later part is pure romance, to show my devotion to Yukino. This is not a System story. Even here, the System is fretting like a doting mom and playing matchmaker, lol.
