After I Transmigrated Into a Book, the Female Lead and I Fell for Each Other

This is my first time writing a story, so it might not be very good, and my writing may be lacking. Please bear with me.

Story blurb:

Bai Liyue transmigrated into a book, becoming the same-named supporting character in Cultivation World, who loved the male lead, secretly pined for the second male lead, framed the heroine, and was ultimately tortured to death by her. To avoid repeating the original story's tragic ending, Bai Liyue completes the missions assigned by the System while constantly winning over the male and female leads. Just as the story reaches its finale, Bai Liyue thinks she can finally bow out after a job well done, but the leads have other ideas.

Chu Nanfeng (looking bashful): Yueyue, I think I've fallen for you.

Mo Wanshuang (looking pitiful): Yueyue, you were the one who came after me first. You have to take responsibility...

Bai Liyue (furious): What is this supposed to be?! Male lead, aren't you only gentle with the heroine?! Heroine, what happened to your cool, aloof persona?!

Chu Nanfeng and Mo Wanshuang: You're more important.

Bai Liyue: ...

Chu Nanfeng and Mo Wanshuang: So who will you choose? You can only pick one.

Bai Liyue (instantly bashful): Then I'll choose the heroine. Who doesn't love a beautiful older sister?

Mo Wanshuang (looking adoring): Good girl~

Straight-laced, self-converting heroine pursuer x pitiful, innocent supporting character pursued

Reader's Guide:

1. Both are each other's first and only, one-on-one, happy ending.

2. In the original story, Bai Liyue liked the male lead at first, then fell for the second male lead after realizing she had no chance with him.

3. The male lead and second male lead are both just plot devices, and neither has any relationship with the heroine.

4. There will be a little angst later on. Don't worry, I won't make it last long.

One last time: This is my first time writing a story, so it might not be good, and my writing may be lacking. I'm not making you read it. Thanks!

Theme: Even when terminally ill, keep your heart turned toward the light.
