Here’s why:"Kung maari po" means “if possible” or “if it’s okay with you.” It’s a polite way to ask permission to share good news."Ipagpaumanhin po ninyo" means “I apologize” or “I beg your pardon.” It’s not appropriate for sharing good news."Naniniwala po ako" means “I believe.” While it’s a positive statement, it doesn’t fit the context of sharing exciting news.
