Heddiw ar S4C Today on S4C.
Mae tymer ddrwg ar Rhian Haf heddiw, yn rhannol am iddi golli allan ar bryniant y ty. Ond mae ei diwrnod ar fin mynd o ddrwg i waeth wrth i Robert Dilwyn gyhoeddi newyddion sy'n mynd i greu rhwyg yn y teulu unwaith eto.
Rhian Haf is in a foul mood as she goes about her business today, partly because she has lost out on the purchase of the house of her dreams. And it seems that her day will go from bad to worse as she gets more agro from her student tenants and their wonky washing machine.
