Retsym the Nam is Myster the Man! Spoiler alert. :)
I think we need to see Lone Mother 4, Housewife 2, Goodtown Mystery 2 but with mom and son instead, Recently Divorced 2, remake of Seashell Whispers, and lastly, a sequel of this game called Not Without My Mother. MC and his sister return to their country to save their awesome mother. :)
