Yuuji and Shana's class is on its way to a shrine for a school field trip. During these trips classmates sometimes take the opportunity to confess to their hidden crushes, and this trip is no exception! Mataka is considering confessing to the one she dreams of, Eita, but her nerves and other obstacles stand in the way: their group leader gets nauseous on the bus and Eita seems to be "really close" with his best friend. Will she find the confidence to confess and wedge herself between Eita and his best friend?
Alisa Mikhailovna Kujou is Seiren Private Academy’s “solitary princess.” She’s a half-Russian beauty with silver hair, at the top of her class, student council accountant, and…completely unapproachable. For some reason, she’s also taken on the responsibility of reprimanding the slacker who sits next to her in class. Masachika Kuze is constantly frustrating her by falling asleep, forgetting his textbooks, and just being an overall unexemplary student. Or at least, that’s how it looks from the outside. She may put on a tough act, but she doesn’t mind Masachika as much as others would think. She even lets him call her by her nickname, Alya. Anyone hearing the comments she mutters in Russian under her breath might know how she really feels, but since none of her classmates understand the language, she’s free to say whatever she likes! Except…there is one person who knows what she’s saying. Masachika eavesdrops on her embarrassing revelations, pretending to be clueless, all the while wondering what her flirtatious comments actually mean!
