We've been dating for a year, and started living together two months ago.
When I stepped out for a quick shopping trip and came back, a strange woman was clinging tightly to my lover, Rin.

What's more, the woman calls Rin "Mama," and instead of leaving, she seems dead set on moving in with us.

Take back my lover?
Stop this bizarre mother-child game?
Or... will you too get swept up in this relationship?
