Gifted junior sister x unserious senior brother
The junior sister is Penglai's most talented disciple.
She is steadfast in her cultivation and never slacks off.
Until she is badly injured and brought back covered in blood. Everyone tells her: You have forgotten someone.
The junior sister is genuinely confused. "Who?"
"Your eldest senior brother."
First meeting
The moment she sees him, the junior sister is certain: There is no way this man could be her eldest senior brother.
He spouts nonsense, grins and jokes without an ounce of seriousness, and is so foolish it's beyond belief. He'll believe even the most obvious lie, and the only thing she likes about him is his handsome face.
She has always looked down on him as foolish, frivolous, weak, and easy to bully.
No matter how everyone tries to persuade her: Her eldest senior brother once spent a fortune for her, braved heaven and hell for her, and gave her everything she needed, from her clothes and meals to her sword...
She remains unmoved.
No matter. He can prove his sincerity, while she follows her path to save all living beings.
One ordinary day, half of her lost memories return.
Decked out in expensive gifts, the junior sister guiltily reaches out to him. He really does seem to be her eldest senior brother.
And she was the one who chose to give him up first.
Later
When he learns the truth about the junior sister's amnesia, he squeezes out two crocodile tears and plays the abandoned senior brother, sobbing:
"I knew it. The junior sister has always looked down on my love, and on me for being weak and easy to bully. Fine, then. I'll leave Penglai and give up being your eldest senior brother~"
At a loss, the junior sister steps forward to comfort him.
The eldest senior brother immediately wipes away his tears with a grin and steals a kiss.
"Junior sister, why are you still so softhearted? What would you do without me?"
The junior sister puts on a false smile, beats him up, and tells him to get lost.
And then he really does leave.
No matter how thoroughly she searches Penglai, she can't find a trace of that shameless man.
At last
She finds him unconscious in a pool of blood.
So he really isn't her eldest senior brother.
She thinks:
So what?
Even if he dies, she will marry him in the underworld.
Theme: She may have lost her memories, but love remembers.
