Isekai / RPG game like / Fantasy World fever 5

Became future trash ML's sick sister. Plan to Raise og ML properly and cure her uncurable disease by spending time with the only cure, the 3rd Prince and future Emperor. Solution: contract engagement!

Act naive but clearly is not MC. She's a geniun good heart though. Tsundere lil brother (og ML) but devoted. Naive ML (feels guilty for the contract bc everybody him included think MC trully loves him and selflesly helps him withuot ambition). Cutty pie og FL (kid).
Overall average but ok.

Middle age lady isekaied as young noble lady. Fell in love and is now relentlessly pursuying her ex-fiancé's Grandpa.

Hilarious. Kinda 4 koma(each chapters are very short). Handsome Power grandpa x Blunt young lady (middle age in her mind). Granpa is feared and respected by all. But he is... Scared of her? XD
The ex-fiancé (trash?) and his brother (cuty) add quite a fun dynamic to this all haha

Became novel extra. Befriended Og FL but she cheated with her trash fiancé? Letting them be she proposed a contract with OG ML. But why does things seems to get more and more commplicated?

Smart level headed MC x Cursed (dragon) Prince ML. OG FL is... weird? ex-fiancé is a serial cheater trash. Seems usual "about to go full angst before fluff" plot. Beautiful art though.

Became game extra but heroine keep steeling her fiancé. Then somehow Crown Prince (FL 1st crush) asked her out? One who refused FL, why not give it a try? Revenge is always a nice side dish.

Level headed MC, had to deal with 4 trashs+ Green tea FL. Not sure about ML yet but he seems decent lover at least. Seems average but bitchslapping are always nice.

Became famous writing her past life beloved fairytale. When she met her old world favorite author, she was determined to publish all his fairytale!

Wild storm MC x Calm ocean ML. Both are quite sarcastic it's quite fun reading their banter. I like the unique poetic spin focusing on fairytale based on real life experience. Just the beginning but I hope it won't become blend, I've got expectation for this

Became Tragedy FL's twin. Married the villain to avoid all tragedy. Luckily both fell in love but... what is this omnious feeling, that not everything is as she though...

I though it would be classical isekai shoujo plot, I was wrong. Huge mystery plot behind why she's here (is this really isekai?) + she kept getting odd memories from og body. Same for Og ML. Og FL seems to know way more than she shows too. Cute ML, the only one without the odd past not really past memories shenanigans so far.

Trapped as horror game FL in an empty cursed mansion and kept dying. Until the final boss came. To stop being haunted by her every death in his dreams, they choose to cooperate.

Poor ML's way more traumatized by her death than MC. OP ML but with heavy presure on his shoulder. Weak to strong (mage) MC though she still can't avoid death everytime. Kind of interesting concept I'm curious if this will bring novelty?

Transmigrated as villlainess. ML, a beastfolk, was disciminated for being a mutated white leopard. Ran away and was capture as slave in all human country. MC decided to take care of him to avoid death.

Transmigrated as the scandalous and hated noble lady. "Since everyone care about me so much", Choose to use her fame to make money as a designer.

Meek shadow to make other shine in past life. Now a power lady striving for freedom. I feared ML was trashed but he turned out descent though a bit cliché. Enemy to lover??? I guess? Classical plot but the art is so gorgeous. And I like the message of Healthy bondaries and woman liberation (though a bit naive sometimes).

Fantasy romance lover transmigrated! But what novel is this? As her flag keep failing and plot twist keep confusing her. Will she finally find her role in this world?

Was confused at 1st and even disliked MC for being so silly, but then around ch15 I realized... This isekai is actually comedy gold XD Once this world mystery start apearing and plot start advancing, I really started enjoying this. It is an unconventional isekai I guess haha! Her sis is so cute. Teasing ML.
