Is Jacky Cheung's blessing a love song?

The time for blessing to turn into a song is similar to kissing goodbye.

According to the meaning of these two songs, it should be such a story:

A man and a woman love each other, but for various reasons, they want to break up. The woman may go abroad, she may go to other places, and the two will break up. Maybe the breakup was initiated by the woman. The man agreed, but he couldn't bear to part with it, hoping to go back to the second time one day or so.

It can be seen from here that this song is really a love song.
