Some Taiwanese no doubt have an overly idealistic and simple view of the intentions and priorities of some western countries. Many actually believe Trump cares about them and will have their back if reelected, for example. Trump couldn't even find Taiwan on a map.

My concern is he would see Taiwan as a bargaining chip - to be traded away in 'the art of the deal'. At least Biden made some semi-doddering remarks about militarily defending Taiwan (which his team tried to walk-back), but I haven't heard anything from Trump on that score.
