Yozora no Sumikko de

Yozora no Sumikko de is a Manga originally published in a Japanese magazine. Hoshino, a timid and unassuming grade school teacher, reunites with his former high school classmate, Sudou, after more than a decade. To their surprise, Sudou's son becomes Hoshino's student, forcing them to confront their unresolved feelings for each other. As they navigate their complicated past, they struggle to recall the events that drove them apart in high school, while the unrequited emotions they still harbor for each other become increasingly apparent. Despite their differences, the rekindled connection between Hoshino and Sudou may be stronger than they initially thought.
