Shi Yao (initially the junior sister of Langyue Peak in the Yaoguang Sect, later ???): Cute and proud, plays the pig to eat the tiger, stubborn, and has always known her true identity. She has always loved her senior sister, Ye Nong, but because she knows she will return to her original position one day, she buries her love in her heart. Highly skilled with the sword, unbeatable at first. Later? (You'll have to guess.)
Ye Nong (senior sister of Langyue Peak in the Yaoguang Sect): Gentle and devoted, highly skilled with the sword, and incredibly indulgent toward her junior sister, Shi Yao. At first, she thinks her feelings for her junior sister are familial, but later she realizes she's in love and accepts it. Unfortunately, their identities stand between them. Is her junior sister still the same junior sister she knew?
Yun Hanyan (senior sister of Yun Chu Peak in the Yaoguang Sect): Cold on the outside, warm on the inside, highly skilled with the sword and somewhat skilled in medicine. At first, she is pure-hearted and detached from worldly desires. After meeting Jiang Yueli, she is drawn to her personality and slowly falls in love with her. In the end, her reserved, scheming nature is revealed, and she captures the little fox, Jiang Yueli.
Jiang Yueli (a disciple of Luoyang Island traveling abroad): Alluring and charming, flirtatious on the outside but pure-hearted within. She's very capable too, but at first she lets her guard down and is tricked by a villain. By chance, she is rescued by the three women on a mission down the mountain. Since they're all pursuing the same goal, they travel together. Along the way, she loves teasing the icy beauty Yun Hanyan, but later Yun Hanyan turns the tables on her, leaving her blushing bright red every time.
I'm new to writing and don't know how to write a synopsis, so I've just introduced the four protagonists. This isn't a popularity contest; there is a main couple and a secondary couple. Feel free to have a look and leave a comment or a suggestion.
Both couples have happy endings. The supporting cast includes men and women. The men are all minor characters who die after a brief appearance. If they don't die, they're good people.
Theme: I don't know.
