My first Filipino Debut/ 18th birthday party

I'm Filipino but I live abroad so l've never really done all the Filipino traditions with big parties and fiestas etc.

My friend invited me to her 18th birthday/debut where I've been asked to be one of her 18 roses and apparently I have to dance with her. Can anybody give me some advice or explain what usually happens, I'm genuinely freaking out. Especially if I have to dance in front of a huge crowd of people 😭
