I know this sentence makes sense in English. But does it make sense (or carry the same meaning) in Indonesia? Is it right to say someone feels 'hangat' towards another person.
That is possible but in Indonesia people use manis in that case. Salam hangat, nama ana
can bu used as signature for a letter or e-mail to a person you already know (very) well. Selamat manis, nama anda for a person you know very well and like.
For people kepada is a lot better and more polite than terhadap.
