My Tiny Senpai

When Shinozaki started his new job, he never expected his superior to be so…cute!? He was struggling to learn the ropes until Katase, his adorably tiny and kind senpai, took him under her wing. She goes above and beyond to ensure Shinozaki feels comfortable—even rubbing his shoulders when he’s tense. But as they grow closer, Shinozaki hopes her devoted attention might mean something more.
