Is There A Harem Ending In 'NEET Receives A Dating Sim System'?

I transmigrated into a dating-sim otome game where I was supposed to romance a soft, fragile male lead. I had finally pushed him onto the bed and was just about to make my move when the long-missing system finally popped back online. [Host, I sent you to the wrong game. This is a horror game.] [The man you’re bullying right now is the horror game final boss.] I lifted my head and met a pair of blood-red eyes staring straight at me. My smile froze. “Um… you look a little tired. Maybe we should… continue this another day?” He smiled back, calm and terrifying. “I’m not tired. Go on.”

～I was a good looking prince when I was reborn, and because I could do indecent things as much as I like, I decided to make a harem while travelling with a beautiful female elf~ Formerly a gamer, the hero who was just reincarnated became a handsome elf prince of another world.

Main Characters:- Alan vi Alling: The main character of the Novel. An otaku who died as the Virgin in his previous world but was reborn as the Elven Prince.

After I transmigrate into a Gary Stu novel as the evil male supporting lead, a system appears in my mind. It tells me that as long as I can conquer one of the female leads, I will be able to return to my original world with a healthy body. But I've failed in my conquest. There are a few female leads in this novel. There's the fake heiress, Leslie Jackman, who I have grown up with and have viewed as my older sister. The true heiress, Miranda Suller, is a boxer who happens to be seatmates with me during our high school times. My childhood sweetheart, Catherine Langdon, who's also a genius surgeon, happens to be one of the female leads too. Heck, even my own daughter, Natalie Jackman… my own flesh and blood… All of them are quick to fall for Gabriel Linner, the poor yet strong-willed young man who's also known as the Gary Stu of this novel. Because of that, they hate me deeply. The system sighs before telling me that as long as I can die in the hands of any of the female leads, it will let me return to my original world. Later on, I use all of the tricks up my sleeve and succeed in getting killed by the female leads. But why is it that they've lost their minds after I die?

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 love you, I really really do~ please marry me" I closed my eyes in fear as I kneeled in front of the devil itself who had his hands warped around the female lead. The next thing I knew I stood in the wedding hall wearing the white suit while in front of the Villain itself putting the ring on my finger. "Now I declare you as husband and hu-husband? you may kill your husband" It was supposed to be a straight Otome game where I was supposed to be dead while saving the FL. But here and I married to the villain itself. "WHEN DID IT TURN INTO BL?" I don't own the cover as I just did the editing of the art and credit goes to its owner

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?
