Kenta doesn't believe in happy endings anymore. When his last boyfriend married a woman, he gave up on the world. Now he keeps himself hidden away in the comfort of his apartment, his only social contacts a few chat friends that he never sees in person. He's become what the Japanese call a hikikomori, a shut-in, and he tells himself he's happy that way. Most of the time he believes it, too.

It's not until he's forced to let an unexpectedly attractive technician into his apartment that he remembers how much he's missing. Gradually, Akira lures him out of his shell, gets under his skin, and makes him face the big wide world again. It's scary and thrilling and fascinating, and before long Kenta finds himself irreversibly drawn to the other man.

Akira isn't interested in the casual sex Kenta offers, though. He wants the whole package, and Kenta doesn't know if he's ready to leave his hikikomori ways behind. But if he doesn’t face his demons, his one chance at a happily ever after might just pass him by forever.
