After ten years of agonizing, Natsuki and Haruomi find love in each other at last. Now boyfriends, they celebrate each other's birthdays, think about their future together, and spend their days in peace and happiness. That all changes, though, when Natsuki is sent on a six-month business trip to Fukuoka. At first, Haruomi thinks he can deal with the loneliness as long as they stay in touch. It'll be nothing compared to the time they were apart, right...? But, that becomes a problem when he's too worried about Natsuki's busy schedule to "bother" him with texts! Just when he decides to update Natsuki on what's happening in his life, they get into a petty argument over it... As their love matures from whirlwind romance to something more enduring, the pair must find a way to reconnect.
