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 sophisticated and austere. And even though Kouta trusts Motoharu and believes he will be faithful, 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?
