What Should I Do If I Mistakenly Capture the Yandere Junior Brother?

(Crazy criticism of the yandere landmine type junior brother x smart complaining type senior sister) Tian Zhi travels to the fairy tale and is the hero's guide, a careful and reliable senior sister. The task she needs to do is to accompany the male protagonist Xie Jianxing in the early stages of his cultivation, sacrifice her life for him at the critical moment, and become the eternal white moonlight. The young man is troubled, emotionally unstable, and a rebellious madman. Fortunately, Tian Zhi worked hard and played the role of guide, and the young man became more and more clingy to him. The plot was progressing smoothly and steadily, but one day the system suddenly received shocking news - she admitted her mistake! The male protagonist Xie Jianxing, who is scheduled to be captured, has not yet entered the apprenticeship! Tianzhi was stunned and looked at the young man in front of her, "... You, you are not Xie Jianxing? Who are you?" The young man didn't take it seriously and gave a sparse and ordinary answer, "Senior sister, I can be Xie Jianxing. I can be anyone, as long as it's the person you love." "So the next days." The young man walked up to her, gently pinched her cheeks with his hands, and looked at her strangely, "You don't need to see anyone else, just me." "What did you say..." Her vision gradually blurred. "——Okay! It's agreed." His tone was light and cheerful. * Yes, when the boy finally realized that Tian Zhi would leave him, he went crazy. But... Ha, haha, is it crazy to be crazy? So what. Wouldn't it be nice to live in a world with only two people? But one day, Tian Zhi suddenly disappeared from their little world... She died...? No... She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive She's still alive!
