Always quarreling, what song is forgiveness?

Forgiveness in quarreling is Li Lele's 5 1 forgiveness. The lyrics are as follows: Is there such a good way to extend the shelf life of love? I thought about letting go at least 50 times and always forgiving when quarreling. Is there such a candy that will make love sweeter, although I have thought about quitting 50 times, and every time I compromise and make up.
