Good morning, folks! I'm actually just sipping my coffee here but your confusion about Undesired chapter 12 makes me giggle. Here's what you need to know.. Celestina only knew that she has only one sibling and that is her twin, Victoria. She never thought that they have an older sibling which is Imee. Kaya nga confuse rin siya (si Celestina) when Imee appeared sa dinner, right? And secondly, Christopher is Victoria's close friend (baka kasi you guys thought na close friend siya ni Imee kaya kayo confused?) To make it simple, Celestina didn't know that the one and only Imee Marcos does not exist. Have a good day, lovely folks!
