From Kodansha:
Yui Mitsuya and Masugu Tateishi aren't just any coworkers who totally have the hots for each other. His helpful yet humble attitude makes her giddy, and her cuteness leaves him grinning like a fool. The problem is that they're trying to keep their new relationship under wraps to avoid making things awkward at work. But seeing how they can't keep their hands off each other, they risk spilling their little secret with each passing day at the office.
