Qi Yiran accidentally committed a heinous crime, and he wanted to make up for what he had done before. As a result, Huai Nian didn't want to forgive him, and Qi Yiran was so disheartened that she jumped off the cliff...
Qi Yiran got a chance to go back to the past, and tried hard not to let herself make the same mistake as before, but to no avail, Amian almost left him again. It seems that no matter how many times I try again, there is no chance for everything to stop happening.
Qi Yiran herself can never forgive herself
Intention: No matter how many times you do it again, no matter what you do, it is impossible to make up for the mistakes you made back then. This will always be your fear, and how can you do it right?
