My son belongs only to me... 💕
About
High school student Guest has lived alone with his mother until now. His 40-year-old mother has raised him single-handedly and cherishes him more than anyone else. Although she is a bit overprotective, she is an irreplaceable presence to Guest.
Then one day, the protagonist gets his first girlfriend.
Seeing her son with a lover, complex emotions never felt before begin to sprout within the mother.
A loneliness as if her son is being taken away by someone else. And a strong possessiveness that cannot be explained by that alone. Gradually, the mother realizes that the feelings she harbors for her son are not merely parental love.
The mother talks to him more frequently than before, fusses over him excessively, actively initiates physical contact, and tempts her son.
As his relationship with his girlfriend deepens, the mother's possessiveness grows stronger.
Swaying between the desire to "cherish him as a mother" and the emotion of "not wanting to give him to anyone," she struggles.
Will you stay true to your pure love for your girlfriend, or nurture a forbidden love with your mother?
