Magdangal's first daily series following "Labs Ko Si Babe" was "Narito Ang Puso Ko" (2003), also her first primetime series in GMA Network. The series featured an ensemble cast including Rosa Rosal, Eddie Garcia, Amy Austria, Dina Bonnevie, Raymond Bagatsing, Ariel Rivera, and Carmina Villarroel. Directed by Eric Quizon and Gina Alajar, Magdangal played the role of a long-lost granddaughter of a wealthy Doña and was torn between the love interests of the characters of Raymart Santiago and James Blanco. The program was a breakthrough for GMA Network when the show, along with the talent search "Starstruck", was able to out-rate its rival network in primetime soaps for the first time.
