Alya Sometimes Hides Her Feelings in Russian

Alya Sometimes Hides Her Feelings in Russian (Japanese: 時々ボソッとロシア語でデレる隣のアーリャさん, Hepburn: Tokidoki Bosotto Roshiago de Dereru Tonari no Ārya-san), abbreviated as Roshidere (ロシデレ), is a Japanese light novel series written by SunSunSun and illustrated by Momoco.

Alisa Mikhailovna Kujou, nicknamed Alya, is a high school girl with silver hair who looks so beautiful that she turns heads wherever she goes. Masachika Kuze, who sits next to Alya, is an unmotivated student who just sleeps at school. Alya often complains about Masachika but occasionally makes flirtatious remarks in her native Russian language. However, she does not realize that Masachika understands Russian.
