Paying load ahead of time TONIK

Hi! Any Tonik loan users here? I am thinking of loaning just because my salary is going to be delayed for the next two months. And I need the money to pay rent now. Question: Possible kaya na bayaran ko ahead of time yung loan na 20k once nakuha ko na full salary ko in the next 2 months? Sorry, kinda dumb about loaning since first time ko tong gagawin.
