Explain in detail: I have always loved it deeply, but there is no reason to be shallow.
Why? You see, the first part is "drunk" and "loved", which means that there is no result with the protagonist, and it is all over; The bottom line is "if you" and "if I", that is to say, the hypothesis is not valid. Maybe it's all an afterthought. I really loved it at that time, but everything has become the past, just to be remembered!
True feelings are caring for each other and being together in this life. There is no earth-shattering, only a long river in it, flowing eastward endlessly.
