I read this manga like a year ago and there weren't many chapters available so I don't know much about it.

The manga is about a girl who was hated by her family, after they went bankrupt she took care of them and worked to make money but sadly died. She went back in time and wanted nothing to do with them but her brothers (or at least 1 of them) remember the past and want to take care of her and protect her, they feel regretful for the way they treated her, especially since the sister they did show love to abandoned them after the bankruptcy.
I think the possible ML was introduced early on too because she relied on someone but I don't remember.

If you know the name I'd appreciate it, if you have a recommendation for something with similar themes please also let me know. The premise it very interesting
The only one that kinda similar is "Lady Isabella's Path to Happiness" but the one I'm looking for was in modern-day.

Please and thank you!

I found it - My Brothers Dote on Me or The Real Daughter of the Qin Family

I'm just gonna list all reincarnation/transmigration or regression manhwa/manga/manhua that i know. Some of these are modern-day reincarnation and simply just reverse isekai..

— The Princess After The Revolution
— The Villainess's Debut Novel
— See You In My 19th Life
— The Princess Is A Gangster
^^(this is more like a modern-day fl transported into an alternate universe)
— My Daughter Is The Final Boss
— It's Time To Stop Looking For A New Family
— Marry My Husband
— Rewriting The Villainess
— As If Love Doesn't Exist
— Tenants From Another World
— My Reason To Die
— My Dear Hunny Bunny
— Don't Call Me Lady
— My Brothers, The Protagonists
— Post-Possession Damage Control
— Spicy Wife's Reborn World
— Destroy Everything
— Trinity Wonder
— Dead Mount Death Play
— School of the Malice
— Only Hope

I don't remember if one of these involve regression (reborn/reverses time) in a modern-day world. I think there are lots of sneak in these list 🤔 if you found what you're looking for, do tell me!

It's a bit on the gate-fantasy side but My Brothers, the Protagonists has the main character sister work herself to death for her family and the regressor brother.

Thank you for the recommendation, I haven't heard of many of them so I've got a lot to read.

@kaloo
The one im looking for is a chinese manga. But thank you for the recommendation, theres more family regression manga than I thought

Do you remember where you read it?

No sorry. I use different sites because sometimes a site I use is missing a chapter

I think I read something like that (if it sounds like what you are looking for then I will try to figure out the title)

Is she the only one working while all her brothers are at home? The brothers are strong but not getting jobs.

I don't remember about their job situations. I don't think the brothers were stong, maybe financially before the bankruptcy.

One that you might be thinking of is "I Was Reborn as a Housekeeper in a Parallel World!" MC worked and all her brothers were stong one way or another, but in this one the brothers are siscons, they just don't want her to find a lover.

A few questions that can help narrow down the search

-Do you remember if it was color? Long strip? pages? Official English?
-Anything about the character's appearance?
-Do the siblings live together?
-What is the MC's or ML's job?
-Are they already in debt? (after regression)
-Why did they go bankrupt? (was it excess spending by parents? the other sister?)
-Are her parents alive?
-Other than the regression are there any other fantasy/supernatural elements (monsters, mind reading, spirits, magic etc)
-Are all the characters human?

So, I randomly got a manga-recommended on some site and I found exactly what I was looking for.
It's called "My Brothers Dote on Me" or "The Real Daughter of the Qin Family" I forgot some facts like MC is actually a reader in a book who entered it and not originally from the world so it's not a time regression story but a transmigration with time regression elements from her sibling characters.
I'm just glad I finally found it cuz it's been at the back of my mind for ages
Thank you

Thank you for trying but I found it. It's actually transmigration into a book with sibling characters remembering more than the book told MC so that's why I thought it was regression
