Did that girl let you cross the threshold? How to answer?

Answer each other sincerely first, and then say some of your own ideas. Is it a metaphor that a girl asks you to cross the threshold, which means that you have reached my standard? Have you crossed the threshold in answering the girl's composition? First of all, you should reply to each other sincerely, and then reply with your own ideas on how to reply to what girls say. For example, I have been trying to reach your threshold, hoping that through more exchanges and getting along, you will feel my sincerity and concern.
