Shogakukan’s Petit Comic magazine announced in its September 2025 issue that Enjouji Maki’s Zenbu Hatsukoi no Sei da (ぜんぶ初恋のせいだ ) manga will end in two chapters.
Manga author Enjouji (Amaku Naru Made Matemasen, Tsumari Sukitte Iitain dakedo) started the manga in March 2024 in Shogakukan’s Petit Comic magazine, and Shogakukan published the manga’s first tankoubon volume in August 2024 and the third volume in June 2025.
The manga follows Urara, a thirty-something woman who would rather skip all the romantic niceties and go straight to marriage. One day, a university student, Suwa, suddenly confesses his love to Rei. He’s a transfer student with a straightforward personality, but he’s younger than her, so of course, he’s out of the question! But he won’t give up on her…? A romantic comedy about a doting man who dotes on her.
