The World's Best First Love Season 1

The protagonist Ritsu Onodera and Saga Masamune (later renamed Takano Masamune due to his parents' divorce) fell in love at first sight in the library when they were in junior high school. The reason was that Masamune helped him get books from high places. Afterwards, Ritsu Onodera obtained Masamune's name from the library and began to borrow books he had read and conduct various tracking behaviors to enhance his understanding of Masamune. (In order not to be discovered, he cautiously used a false class and pseudonym - Ritsu Oda - when borrowing books. This is also the reason why Takano failed to know Ritsu Onodera's identity when he applied for a job). As a result, after three years of bitter love, Onodera met Saga's hand while borrowing the same book in the library. He was at a loss and confessed to Saga-senpai. The two had a short but profound love in a dramatic way. Because Saga-senpai thought Onodera Ritsu was cute and silly, he chuckled (actually to cover up his shyness), causing both parties to misunderstand each other, and they broke up. But the cold-hearted Saga senior has a deep love for Onodera Ritsu, because Onodera Ritsu has always been warm to Saga Masamune.
