Overview:
When one late night of overtime leads to a spicy fling, your long-lost feelings for your office rival unexpectedly resurface! What bottled up feelings will this predicament reveal? Will it reignite your long-lost feelings for Nanako? Where did it all go wrong between you and her? Will you reconcile with her to see if there's something more? And how will she eventually help you to reconnect what you've lost in touch with: that there is more to life than just being a productive workaholic?
