Tomb Raiding: I Transmigrated and Became Little Brother's Guard

Also known as: Tomb Raider Notes: A Happy Ending After the Break

What should I do if I think this title sounds awful? It's already been recommended.

This is a dual-female-lead story. The protagonist disguises herself as a man early on. There'll be unrequited feelings in the beginning, but everyone will end up paired off later.

Before transmigrating:

I had no one to care about and no friends. I was just someone else's weapon, a genius willing to let herself go.

After transmigrating:

“Ayou.”

“What is it? I'm here.”

“I love you.”

“I love you too. It has nothing to do with gender. I just love you.”

“I'll be your weapon.”

“You don't have to. Because I love you.”

“Master.”

“Hmm? What is it?”

“I'll protect you and be loyal to you forever.”

“Mm. You've said that plenty of times.”

“Well, well, Young Master Xiao Chi, look who's finally blossoming! Never saw that coming! Don't forget to invite Yun Cai and me to the wedding banquet!”

“Sure.”
