Ano Yoru ni wa Kaerenai

Summer, a social worker, is broadsided when Darius unexpectedly shows up at her office. He broke her heart seven years ago, but he has his own security firm and is here now to update the office security system. Worse, Darius has the gall to act as if nothing happened between them! Why did he break up with her in the worst possible way? She can’t trust him again until she knows the reason for their breakup. But at the same time, she can’t deny that she’s attracted to this new, even sexier Darius.
