Celyn (Kim) and Margaux (Maja) are caught in a bitter feud, initially over Celyn's falling for her best friend's partner (Enchong Dee). Their tiff later escalates with the revelation that Celyn is the biological daughter of Margaux's apparent foster parents Beatrice and Julio (Janice de Belen and Ariel Rivera).
The rivalry of the two lead characters intensified with the revelation that they are in fact biological twins - the children of Julio and Beatrice, given birth to by the latter's half-sister Theresa (Cherry Pie Picache), who had volunteered to be a surrogate mother.
In the latest episodes of the series, Margaux's hatred towards Celyn grows when herfriend and confidant Liam (Xian Lim) falls in love with her twin.
The warring sides, however, are set to finally reconcile, as seen in a preview released Wednesday night (see above) for an upcoming episode of "Ina, Kapatid, Anak."
A tearful Margaux tells Celyn:
"Hindi ko alam kung paano ako hihingi ng tawad for hurting you. I'm sorry, Celyn. I am so sorry."
The soap first aired in October last year, and was already billed at the time as featuring the "rivalry" of the two principal characters.
It was in early January when Kim expressed regret over her "wasted" friendship with Maja, following reports of a blooming "relationship" between the latter and Kim's ex-boyfriend Gerald Anderson.
Kim said early this month that she has forgiven both Maja and Gerald, who are now more open about their relationship, but added that what they did is difficult to forget.
