Alya Sometimes Hides Her Feelings in Russian, Vol. 2 (manga)

I don't mind if I have to be alone. Alya has an adorable habit of revealing her feelings for Masachika when she teases him in Russian, thinking he can't understand her. As it turns out, those feelings began all the way back in middle school. She didn't always think so fondly of him, though. At first, Alya only saw him as a slacker, just like so many of her peers. But when her classmates left her high and dry during school festival prep, the one who reached out to thaw her frozen heart was the last guy she would have expected.
