I Became the Younger Sister of a Regretful Obsessive Male Lead


Links are NOT allowed. Format your description nicely so people can easily read them. Please use proper spacing and paragraphs.

I’ve transmigrated into the world of the BL webtoon where I left my one and only spiteful comment. On top of that, I become the adopted younger sister of my favorite character: the obsessive male lead who is later regretful for his actions, but still dies along with the duke in the end. So, I was determined. Since I have transmigrated into this world, I can’t stand by and watch my favorite character die. Additionally, I also don’t want to die. That’s why, author, I’ll need to change the tags and the ending of this webtoon slightly! From to tragedy to HE.

“Brother, please smile like that in front of others as well.” I said to Lucian, who doesn’t smile even a little bit in front of others.


Was that request too out of the blue?

Lucian looked at me with a peculiar expression.

“If you do that, I will give you a gift.”

I said that because I wanted to help him in any way I could.

He looked at me for a bit and hesitated before replying, “A gift… Is anything fine?”

“Of course!”

The moment I gave that answer with certainty, his expression changed right at once to that of a starving predator… Did I make a mistake?

Then, Lucian calmly replied with an expression full of expectation.

“Give yourself to me, Rachel.”

Huh? What did he say? What did he just ask for?

So far, this series is proving to be enjoyable if sad, read. Our MC has set herself a task to help her "brother" find a happy ending. However, the first obstacle is his dad that has a rather large amount of baggage (pretty standard fare for a lot of 'historic' BL series). I am looking to see how the series progresses, especially to see if the old duke can redeem himself.

The novel is very well written and the author explain the character suffering & motivation in such short span of time. I hope Lucian can really change his path to become an obsessive lead and Rachel can indeed find happiness with him in this alternative world. Lucian reminds me of Heathcliff from Wuthering Heights and the passion he has for Rachel has that angst and balance of romance. I really dont like Lucian's father for venting his unrequited hatred on his son for looking like his father and compensated his... more>> unrequited love of his first love by being a father to Rachel. He is seriously psychotic. Thank you to the translator for doing a great job. I wish to read more of this author work. <<less

Hello again, I want to write a review for this one even though I'm a quiet and silent reader.

I will give 3 and a half stars for this one because I'm still currently reading it as the current English translator group has updated this.

The plot of the story is our FL Rachel transmigrated in the world of a BL series that she has read and give a harsh comment on it. She suddenly becomes the adopted sister of the 2nd ML Lucian who live miserably because of the OGML. Rachel... more>> is a fan of Lucian so he wants to change the story plot and make her favorite character happy.

Rachel the FL

  • While reading this I think she has a cute personality.
  • She is the OG antagonist. I forgot to say lol.
  • The Duke or the ML's father loves her so much because she is the daughter of the Duke's lover. (The Duke's lover is a guy by the way lol.)
  • Because she knows the whole story she wants to help the ML to be happy. Even though the future lover of Lucian will be the OG lover or not.
  • She really loves his brother Lucian so she always makes time for her.
Lucian the ML

  • He was really handsome. The description is too detailed that I was mesmerize myself lol.
  • He wants the attention and love of his father. But his father hates him because he is the son of his mother who destroy the lovers love. As I said, his father is gay right.
  • From the start he wants to get close to the FL so he can have his father's attention but in the end. His attention was taken by Rachel and he only wants Rachel attention now more than anything.
  • Because he loves Rachel, he becomes quite obsessive as written on the title if you notice.
I really recommend this if you read the prologue of the story. You will really get hooked.

Short summary of Prologue below.


The ML don't want anyone to touch Rachel even a single bit. But she accept a dance offer from someone and ML gets mad so he throws his gloves in front of that guy. Throwing gloves here is a sign of war or something. The FL gets mad to the point of leaving that place and ML chase her or more following her.


But it will be a turn off if you hate typical obsessive character. Lucian is like that.

Who cares about that if the plot is interesting even if the update is quite few. I still look forward on this every single time.

And our FL is quite smart and understanding so I read a couple of times until new update comes.

As I said just give chance for this one. And I hope this review will give you boost to read this one. Because this one is pretty good.

PS I also recommend other stories of this translation group. They are really great!👍 <<less

As I have read the current update, the story plot is very intriguing, specially when the author describes the characters, their sufferings and they are slowly overcoming the said challenge. Overall, the book is great and interesting.

Edit: Sorry, I accidentally pressed two stars. I am rating this novel to have 5 stars.

I'm quite enjoying the story line, though the premised/original story line was thought-out to be a BL story, which isn't my cup-of-tea, as I read further, it is becoming a reverse harem instead. 🤔 I'll try to keep this novel on tab.

Thanks for translating this novel 🥰
