These construction workers like to play with their tools.
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!
Back when architect Motoharu Maki was just starting out, he nursed a one-sided crush on another—his former mentor Mibu. His current love, Kouta, is shocked to find out that, unlike Motoharu’s usual type, Mibu is a sophisticated, austere person. And even though Kouta has faith in Motoharu’s fidelity, he can’t help but feel a little shaken. What else doesn’t he know about Motoharu, and should he be worried now that Mibu is back in Motoharu's life?
