University Series #2 Hiro, a student pilot from DLSU, was very clear with his number one goal in life. It was to study in the best flying school in Florida. However, he agreed to have a no strings attached relationship with Yanna from FEU Tourism, the woman who cannot be tamed with her sexcapades.

Meet Yelena Rae Falcon, the substitute bride, kayang gawin lahat para sa pinakamamahal na lolo't lola niya na nag-alaga sa kanya mula noong bata pa siya. Kahit pa ang pagpapanggap bilang kanyang kakambal, na ngayon lang niya nakita, para sa kasal nito dahil ito ay nasa coma. Meet Alexander James Hernandez, the playboy groom, hindi naniniwala sa salitang pag-ibig. Kung magpalit ng babae ay parang nagpapalit lang ng damit. Napilitan magpakasal para lang hindi bawiin ng papa niya ang kompanya. Paano kaya mapoprotektahan ni Yelena ang kanyang sekreto at lalung-lalo na ang kanyang puso na unti-unting nahuhulog na rito? At papaano kung bumalik ang totoong nagmamayari? Is she willing to fight her love and prove to him that she is the true one? Or she will just leave and be his unknown substitute wife?
