If a boy changes his signature to be the same as yours, the content is that deep affection is not as good as long-term companionship. Needless to say, deep affection, what do you mean? He also asks us if it is. 1. Coincidence (basically excluded)

He likes you to express your feelings euphemistically.

I just like this sentence, so I used it.

I asked you about your relationship, just flirting with you.

Filter according to your actual situation, and it is better to ask him directly what he means.
