The Supporting Female Character's Conquests [Quick Transmigration]

Liu Xi spent the first sixteen years of her life trapped in a massive cage. Then someone broke her out and brought her into the world, teaching her friendship and warmth. So, during the last three years of her life, she protected that person and gave up her life for him. As her consciousness faded, she vaguely heard a ding before plunging into darkness. When she opened her eyes again, she had gone from a human weapon whom everyone feared to Liu Xi, a novel-hopping agent in quick transmigration. Her mission was to win over the target in each world and raise their affection to above 70.

Former human weapon and quick transmigration agent heroine x System male lead who gradually comes around

1. The heroine's original world is a novel aimed at male readers, where she's a supporting character with an unusual way of thinking.

2. The male lead is unfriendly at first for a reason, but in the end he'll come around.

3. The author is very protective of the heroine. She won't be the one getting hurt.

4. Each world is derived from a novel. Winning over the target isn't limited to romance, and the original couples in those novels won't necessarily be broken up.

5. Both leads have flaws, and this is a quick transmigration story about growing together. The missions are part of the journey, so don't get too hung up on the results.
