When Jun Kurisaka's fiancee, Shoko Sekine, applies for a credit card at his urging, she is denied due to a declaration of bankruptcy several years ago. What's strange is that Shoko is as shocked as Jun: when she disappears, Jun begins to suspect that she's not really Shoko at all but an impostor. Where is the real Shoko? Did she relinquish her identity willingly or was she the victim of foul play? And just who is the woman Jun fell in love with?
