Oji-san, Ore ni Koishite Kudasai

Overview

Akihito Kusunose, an elite corporate employee, finds his nephew, Ren Kusunose, joining his company as a new hire. Ren had harbored feelings for Akihito since childhood, and when he was in high school, he had even confessed his love to Akihito, but Akihito had brushed it off as a typical teenage misunderstanding. When they reunite after five years and Ren tells him, “My feelings haven’t changed since back then,” Akihito is shaken to realize that Ren’s romantic feelings are genuine. His cute nephew has gradually begun to show signs of maturity, and Akihito finds himself becoming more aware of him, but as his uncle, he cannot reciprocate those feelings. One day, while they are alone in the office, Akihito praises Ren’s work, and in his delight, Ren impulsively kisses him. Akihito pushes him away in the moment, but he begins to realize that his feelings toward Ren are changing… A pure romance BL featuring a significant age gap.
