Struggling to discern reality from illusion, he gradually merges with the memories of his two lives, and his sister rushes to his side, brimming with relief at his awakening.

Moved by his genuine sincerity, his sister places her trust in him. As they embrace each other for comfort, Ann Ning realizes the unfamiliar sensation of relying on others, but he embraces this newfound responsibility wholeheartedly.

However, as he assesses his weakened physical condition, he becomes acutely aware of the urgent need to improve his health. Utilizing his alchemical knowledge from his previous life, he resolves to create remedies to strengthen his body. This introspection prompts him to confront his past irresponsibility and recognize the burden his sister has shouldered alone. Touched by her unwavering dedication, he dedicates himself to becoming a responsible brother and protector.

As he contemplates his frail existence, he acknowledges his vulnerability and resolves to change his circumstances, regardless of the challenges and consequences that lie ahead.
