High-flying architect Maki Motoharu loves looking at hot guys, and where better to find a lot of good-looking, well-toned hotties than a construction site? But after one visit, Motoharu winds up with an unexpected commitment. Ironworker Ohki Kouta is young, foul-mouthed, and not at all Motoharu's type!

The building industry is in chaos due to an unprecedented scandal. Mibu, a gifted architect, has left his mentor, the famed architect Shibusawa—both professionally and personally.

Motoharu doesn’t want to burden his lover Kouta with it all, but Kouta has other plans!
