Solo trip to Taiwan and feeling nervous 😅

I’m traveling to Taiwan soon, and I don’t know why, but I’m feeling oddly nervous. Originally, my cousin and I were supposed to go together—she was the one who booked the trip—but she decided not to push through. I figured I’d continue with the trip instead of canceling it.

I’ll only be in Taipei for about 2 days, so I’m not planning to hit every major tourist attraction. My plan is just to explore the city, eat good food, visit a few places, and have a relaxed trip.
I think what’s making me anxious is Philippine immigration. I’m worried they might question why my trip is so short or think it’s strange that my itinerary isn’t packed.

Has anyone here flown to Taiwan for just a day or two? Did Philippine immigration ask about the length of your stay or your itinerary? Am I just overthinking this? I’d appreciate hearing about your experiences or any advice. Thanks!
