The other party wants you to reply so badly.

If the other person misses you too much, you can choose the following reply methods according to your relationship with the other person:

1, you just miss each other, so just express it. You can say, "I miss you, too."

2. If you want to surprise each other, you can reply: "Guess, did I miss you?"

3. If you are not sure about your feelings for this person, you can keep a little distance and answer, "I am really touched by your saying so, but I am not sure about my feelings."
