The Twins Set Me Up, and I Honestly Have No Idea What to Do

Also known as: "Am I the One Who Fights Muzan?", "Just How Many Good Little Brothers Do You Have?", "You Twins Are Impossible to Talk To", "Is It Really Our Fault That We Fell for Our Older Sister?"

Blurb One

An older sister can't become your wife. Once she does, you'll never again be able to look her in the eye without shame and call her "Big Sister."

So an older sister can only be your wife... Oh, no... I mean, a wife can only be your older sister... Sorry... I mean...

Blurb Two

The System crashing would have been bad enough, but she ended up transmigrating into a monster. She really didn't want to put in any more effort.

But how did she somehow end up raising kids again?

Fine, they're adorable, so she'll raise them. But how did her peaceful farming life suddenly turn into an action series?!

"Big Brother, do you like her? She smells so nice, like plum blossoms."

"No."

"But you barely resisted when she hugged you."

"That's because she's strong!" Youichiro snapped, sounding annoyed.

"So, according to our agreement, what should you call me?"

"I never agreed to such a stupid bet."

"Muichiro, look at him. He won't keep his word." She started tattling.

Muichiro chuckled beside them and tugged on his brother's sleeve. "Come on, you lost. Own up to it."

Youichiro glared at him, then glanced at her smug expression. At last, he clicked his tongue and turned toward the door.

"In your dreams."

A few things to know before reading

The story centers on the heroine. I write the characters my own way, with a focus on romance. The ending is an unconventional HE, though it could also be considered a TE.

This is not a wish-fulfillment novel! This is not a wish-fulfillment novel! This is not a wish-fulfillment novel!

The early story focuses on the familial bonds between the Tokito twins and the Sengoku-era twins. [The middle focuses on Gyutaro, and the twins don't get much page time.] The later story mainly features the twins in a love triangle with the heroine.

The main story ends with the Tokito twins' route; the alternate ending in the bonus chapters follows Gyutaro's route.

There are mountains of personal headcanons, and the timeline is a little messy. Anything that doesn't match or isn't mentioned in the original is something I made up.

The author has almost no subjects they consider off-limits, so anything might show up. Please don't buy the whole book at once, in case you run into something you dislike and waste your money.

My writing skills are limited, so please don't offer writing advice. You don't need to tell me if you drop the story.
