My Unfriendly Manager

The handsome model Yura gets a new, stern manager. But his serious and strict character is the worst match for someone as sloppy as him! Plus, he even ends up moving into the same apartment building as his manager, Shiina, after making the decision to "put serious effort into work"...! Even though he thought he'd find this meticulous and diligent guy annoying, Shiina's sincere kindness and his brief smile makes Yura's heart race for some reason... They're so close to each other, but nothing's happening... a slow burn romance story.
