What's the difference between "hehe" and "hehe" in SMS reply?

Personally, I think replying hehe is more popular! That is to say, it is more suitable for everyone, and sometimes there is nothing to say, or just deal with it! But replying hey hey is different! The explanation is from the heart and feels very kind! Also more playful! That means she's starting to get interested in you! As for punctuation marks, I personally think there is little difference, but punctuation marks with ~ give people a continuous feeling, which means you can continue! Wish you success!
