Gakuen no Madonna no Watanabe san ga, Naze ka Maishu Yotei wo Kitekuru

Ryoichi Aikawa is a high schooler who prefers spending his youth fishing in solitude rather than chasing romance. For him, the tranquility of the harbor is everything—until one day he saves a girl from being harassed by some troublemakers. To his surprise, that girl is Watanabe-san, the incredibly popular school "Madonna". Ever since that unexpected encounter, the school idol has somehow taken an interest in Ryoichi's fishing hobby and started asking about his weekend plans every single week.
