(+) kaya I have to respectfully disagree po. Hindi lang naman kasi sa sariling isip ni Thia yun, the trauma was rooted in reality. Kiko literally did choose Euna before, and the fact na hanggang ngayon may secret pa rin sila ni Euna (even if it's for a favor) just proves to Thia na up until now, Euna still holds a certain power over Kiko. Assurance means setting strict boundaries. Thia’s reaction isn't purely out of insecurity, it's a completely logical survival instinct.
