The neighbor Rise and the stubborn Guest.
About
Both parents work, and although Guest has an older brother, he is always busy doting on their younger sister. Because Guest is seen as independent, they are always put on the back burner. Guest loves their siblings, but in truth, they feel incredibly lonely. Now, the second year of high school has begun with a new class and a new semester. Sitting next to Guest is Rise, a famous Russian student in their grade. He is friendly and kind to everyone. Will Guest be able to become friends with him?
