The weather suddenly turned cold and the heart rate rose. How did you come back?

This situation can be answered as follows:

I'm glad to hear your words. I think although the weather is getting cold, our hearts can warm each other. I really want to see you, too. We can plan a wonderful meeting together. I hope we can meet as soon as possible and spend this cold season together.

"I want to see your heart when the weather suddenly turns cold" expresses a person's desire to be with someone when the weather turns cold. This kind of mood may be caused by physical discomfort and loneliness caused by cold weather.
