Nana remains faithful throughout the long separation and is finally there to meet him on the day of his release. Walking home together for the first time in four years, the engaged couple feel strangely nervous and struggle to speak. The moment they step through the door, their restraint breaks. They embrace, confess how long they have waited for this, and lose themselves in passionate sex as if trying to reclaim every year stolen from them.
