As Dyesebel, Marian has to endure staying underwater for long hours. "Medyo nahirapan ako noong una. Yung pagngiti-ngiti, yung pagdilat ng mata, medyo nahirapan ako. Pero habang tumatagal yung taping namin, nasasanay ako. At mas masarap talaga na yung trabaho mo, habang ginagawa mo ay ine-enjoy mo," says Marian.
