The biggest high school event of the year has arrived—the class trip! What was meant to be a sunny adventure to Okinawa, has unfortunately turned into a snowy escape to a local ski resort. While Ryuuji's fellow classmates are managing to have fun and make the most of this curveball, Ryuuji's feelings for Taiga and Minori have him miserable and tied up in knots! And just when things couldn't get worse, Taiga has gone missing...and there's a blizzard about to hit!
