Lin Zhou somehow fell into the sea and traveled to a parallel world with a strange watch, where he became a different version of himself.
First world: A devious, cunning fish × Lin Zhou, who wants to go home
"I killed and burned for your sake, and you actually dare to kill me?!"
The little mermaid clutched her clothes. "Sister, I was wrong. Don’t leave me."
"Forget it. He’s just a kid."
Later, Lin Zhou learned the fish had lived for almost a hundred years: "..."
Second world: Delicate, soft-hearted Xie Daiyu × mischievous Lin Zhou. Beware, there’s a pervert around. A real pervert.
Lin Zhou ended up in Lin Zhou’s body, and his stepbrother became his dream guy!
All Lin Zhou wanted to say was, "Don’t mess with me."
Some fish: "Sister, my heart hurts so much. Don’t get together with him. Like me instead."
Third world: Xie Wan × Lin Zhou. Why does everyone keep trying to kill this young lady?
With his memories gone, Lin Zhou just wanted to study hard.
Some fish: "Sister, I miss you so much."
Lin Zhou held out an outstretched hand. "No way. We’re not close."
Later, the fish went missing, and Lin Zhou was nearly killed. Who?! Who’s trying to mess with me?!
Just because I saved you, you think you can give me your life?
I really don’t know what to say.
