This is obvious. In a relationship, there is always a lot of love but not enough, and there is always a lot of lovelorn. No matter how much you like someone, even if you have a good past, in the end, you can't go on. Losing a person, especially a person we like very much, is of course difficult for us to calm down and it will only be painful. After a long time, I will feel particularly bad and often think of each other. They don't even want to accept the fact that they have separated, hoping to make up and have a future.
