The Dress-Up System Turned Me into a Fairy

[I turned off the comments because I don't want them to affect my writing. Please don't read if that bothers you.] Xia Tao transmigrates with the System from a dress-up game. In her very first world, she finds herself in an elite academy scenario. The System demands that she win over the school's corporate heir. But Xia Tao is just a minor character at the academy: average looks, an average background, and average abilities. She doesn't even get to play the vicious villainess, making her a disposable character who never gets to meet the protagonists. Luckily, the outfits provided by the dress-up System come with magic and special effects. Xia Tao gets an idea on the spur of the moment... She changes into the [Mermaid] outfit. The [Mermaid] outfit comes with an aura of breathtaking beauty, and lets her switch freely between human and mermaid form. Looking at the new blue tail growing from her body, Xia Tao smiles with satisfaction. She decides to pretend to be a mermaid. * Not long afterward, a research vessel belonging to the Shen Corporation captures a mermaid while out at sea: a stunning beauty with golden hair and blue eyes. Staring at the delicate, beautiful mermaid, the male lead feels his heart beat clearly for the first time. Mermaids... really exist in this world? * After completing the first scenario, Xia Tao discovers the true purpose of the dress-up System. From then on, she begins a journey of impersonating fairies and legendary creatures. [Scenario Two] She equips the [Angel Wings] outfit and descends upon a world on the brink of destruction as a pure and immaculate angel. "If the world's evil truly cannot be cleansed, then let me bear it all alone." [Scenario Three] She equips the [Moonlit Osmanthus] outfit and comes riding the moonlight, her beauty clear and radiant, descending upon the peak of a green mountain. "Y-You are Chang'e, the fairy who flew to the moon in the legends?" Xia Tao: Who said dress-up games were casual little games? This is obviously a devastating weapon! Reader's Guide A Mary Sue-style romance-focused story. The heroine will use the dress-up System to impersonate fairies and legendary creatures, such as mermaids, angels, and elves. She will never be found out. The heroine will never be found out. The heroine is an acting genius. On the surface, she's the snarky one, but in truth she's cold and detached. She won't fall in love with anyone, and there is no endgame couple. Not recommended for readers who are invested in a particular pairing, nor for readers who dislike men or women. Theme: There is more than one way to solve a problem.
