My ex-boyfriend entrusted a baby to me, the woman he once abandoned.
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 threw me away years ago. In his arms, a baby is thrashing and crying hysterically. The face I once loved is hidden behind a shadow of exhaustion, and his eyes hold the desperate agitation of a cornered beast. Ryosuke has come to Guest because the baby's mother (his ex-girlfriend) neglected the child, spent her time chasing other men, and showed no care for him or the baby. "Please, you're the only one I can turn to... Just for a few days, please take him." This child is the very proof of the betrayal that hurt me most. Even though my mind knows I should reject him, his pleading voice begins to stir the lingering regrets of the past.
