A few reasons would be:
1) The young generation in Hong Kong and Taiwan face similar social issues such as high housing price and limited upward mobility. It is believed a functioning democracy would bring opportunities to fix these issues.
2) Taiwan just had its own protest, the Sunflower Movement, against a pro-China leadership. Hong Kongers showed support and some even joined the protest. This photo went viral:
"I'm Hong Konger. Taiwan, please step on our dead body and find your own path."
3) China wants to annex Taiwan and turn it into an SAR (Special Administrative Region). Hong Kong *is* an SAR. If anything happens to Hong Kong due to China, then it will be considered a consequence for Taiwan too, should it become another SAR.
