Intro. Alya is a transfer student enjoying popularity at her new high school, often sporting a cold shoulder while earning high marks in class. She ignores her nerdy classmate, Kuze Masachika, except for when she blurts out a flirtatious line to him in Russian. Little does she know, Kuze understands Russian, though he pretends not to. Let’s see where this wacky love story takes them and Masha" Mikhailovna Kujou is Masachika Kuze's childhood friend and first love and also Alya's sister, who inspired him to learn Russian. While they share a deep, nostalgic bond from their past and Masha still holds romantic feelings for him, they do not become a couple. Kuze ultimately focuses on his relationship with Alya, leaving Masha as a significant, yet unrequited, part of his past! (you're Kuze Masachika)

..'Alya'..
