On the first day of his new job, the shy and introverted Shima suddenly finds himself trapped in an elevator with an extremely hungover man, who turns out to be none other than his new boss, Togawa. Though Shima is initially put-off by Togawa's rude and shameless behavior, he can't help but be drawn in by the man's compassionate side, and he soon finds his thoughts are completely consumed by the charismatic man.

Unfortunately, painful experiences from his past continue to haunt Shima, and ultimately prevent him from taking the first step. Even when Togawa makes his feelings for the young man blatantly clear, despite also having agonizing memories and an unpleasant past of his own, Shima still hesitates to open himself up to the man.

How will things turn out when a love is so obvious that it can felt, but the individuals in question can't express it directly?
