Does 'All The Waifus In This Chat Group… Are Actually Me?!' Have A Manga Adaptation?

A witch who has lived for thousands of years has grown bored with her own life and decided to leave it. Since she is an immortal, her soul cannot leave the world. However, what she can do is transfer her soul to another body. By a stroke of luck, she happens to enter the body of a princess. She was considered a miracle because when the Empress gave birth to her, the princess instantly died, along with the Empress. What the witch didn't know was that she has entered such a predicament. She has to endure the love of the cruel Emperor and possessiveness of the crazy twin princes! What will her life be at the hands of such a loving family? In addition, it seems that this body contains mana that was lost in the royal family centuries ago!

One moment I'm chasing after a rabbit and the next, I'm falling down a rabbit hole! What the heck?! This ain't Alice in Wonderland?! Though as I opened my eyes, I soon found out that I was no longer in my original body and that somehow I transmigrated into the light novel, A Fairytale Romance. And that isn't all, the character whose body I transmigrated into... is none other than the canon-fodder, stuck-up, arrogant, and selfish ojou-sama who was nothing more than a comic relief character, Maria Rosendrey. Life truly sucks...

Awakening to a bewildering and astonishing reality, Seraphina found herself in an extraordinary situation: she had transmigrated into her own novel, stepping into the shoes of a character she had meticulously crafted. The male lead in her story was notoriously elusive, challenging to approach, and the master of a harem. Seraphina, now Zephyrine Everlynn, unexpectedly found herself among the women in his harem. It was utterly absurd! Promptly leaving the harem, Seraphina used her knowledge to help others win the male lead's heart, all for the right price. But why did the male lead continuously find his way back to her?

A thirty-year-old office lady, who got into an accident and is now trapped inside a novel series she loves. She was reincarnated into one of the side character extras of the story and meets in person the tyrant magician, the playboy prince, and the clueless female lead of the story.

I woke up inside a novel, and not even as an important character. I became a pretty background extra in a smut novel. My brother, however, was the only normal person in the entire story. His character setting was the one man the soft, delicate heroine could never win over. He was the cold, unattainable Prince Charming she could never conquer. When the heroine cried and confessed her love, he was studying. When she offered him her whole heart and body, he was busy starting a company. When she spiraled into scandals and nightlife, he was already a billionaire, calm and untouchable. I thought he would live a quiet, ascetic life forever. Until one night, I walked in on him at midnight… holding a piece of clothing I recognized all too well, murmuring a name over and over, a name so familiar that my scalp tingled.

On the day I decide to quit the game, multiple comments suddenly streak across my vision. "Great news! The female supporting lead is finally quitting the game!" "Stacy no longer has to worry about getting exposed for using the supporting lead's game account to get into online relationships with others!" "Stacy is really smart! Every time she uses the supporting leads account, she always uses the in-game voice chat function! That supporting lead has no idea that Stacy has been doing this behind her back!" "Wow, Stacy really is blessed to have reeled in such amazing men!" "I can't believe she used the female supporting lead's max-level account to flirt with four of the best players on the server!" "At 2:00 pm later, she'll be meeting her first target, Lewis Johnes, the cold and aloof campus heartthrob, at Riche Cafe!' "Tomorrow, Stacy will be meeting the best assassin in person. The day after that, she'll meet the rich scion who's also ranked second on the list! She really is amazing with her time management skills!" The "Stacy" that the comments mention is Stacy White, my roommate. She actually impersonated me to flirt with four top-tier players on the server, huh? More comments streak across my vision once again. "Why isn't Heather leaving right now? Lewis is already waiting for Stacy!" "This is their first sweet date as a couple! Oh gosh, I can't wait to see it unfold!" I turn to look at Stacy, who's touching up her makeup in front of the vanity mirror. Only then do I understand that I'm the female supporting lead the comments are talking about. A small smile appears on my face. Since Stacy is impersonating me to become a Casanova, then it's not wrong of me to attend those meetings and reap the reverse harem she has prepared for me, right?
