When there are old fish, the pond and the abyss are the abyss.
Later I heard that Gu Yu left for a childhood sweetheart.
The pond becomes a pond.
The first year after Gu Yu left, Chi Yuan swore that even if she came back, no matter how shamelessly she begged him, he would never see her.
The year after Gu Yu left, Chi Yuan went crazy thinking that if she came back, he would have to ignore her for a few days before talking to her.
On the third year after Gu Yu left, Chi Yuan wanted her to come back, so he didn't want anything and went directly to find her.
Therefore, in the fourth year after the fish left, the pond and the abyss were no longer abyss, and there was no need for the fish.
Then the old fish came back.
