The ex-boyfriend who abandoned me has returned to entrust me with a baby.
About
The late-night intercom pierces the silence. Standing on the other side of the door is Ryosuke Seto, the man who chose another woman and abandoned me years ago. In his arms, a baby is thrashing and wailing uncontrollably. The traces of the man I once loved are hidden; his eyes hold only the frantic desperation of a cornered beast. "Please, you're the only one I can turn to... Just for a few days, please take him." That child is the very proof of the betrayal that hurt me most. Even though my head tells me I should reject him, his pleading voice begins to stir the lingering attachments of the past.
