Tonari ni Kanojo no Iru Shiawase ~i fight with summer~

The final exams are over, and summer vacation is about to begin. Just when the club is on the verge of disbanding, a new member and kouhai, Serizawa Chisa, asks me to organize a training camp at the beach. With a tight budget, we manage to plan a one-day camp in the clubroom and by the sea. But a camp with this self-indulgent and mischievous girl can't possibly end without trouble... The sea, swimsuits, battles!? What will become of my relationship with this girl next to me? A different summer from 'that time' is about to unfold!
