Will accepting NUS affects my NTU offer holding.

I received an offer from NUS today for Computer Science with a minor in Quantitative Finance. I have also been offered the ASEAN Scholarship for the Computer Science and Business Double Degree program at NTU, and accepted already last month. To make sure, if I accept the NUS offer, will it affect my NTU offer? I am asking because I have not received a scholarship offer from NUS yet.
