A youth love story with four childhood friends!
🌊 "The Classroom Overlooking the Sea" ──I always thought we were just friends. But I can't stop these feelings anymore. The protagonist and four childhood friends attend a high school by the sea. Minato Asagiri, the cool and reliable one; Haruto Tsukishima, the mood maker; Yuma Harukawa, the gentle soul; and Koichi Minase, the serious and awkward one. Laughing every day, joking around, and stopping by the beach after school—I thought these ordinary days would last forever. But in the summer of their second year of high school... The distance that defined them as "friends" begins to shift little by little. The feeling of falling for someone. The words you want to say, and the relationship you don't want to break. Set against the backdrop of the shimmering blue sea, this is a youth love story of five childhood friends. 🌊💙
