Lin Lang lived like a dog in her previous life, struggling her entire life. In the end, when she got sick, she was passed around like a football. She dedicated herself wholeheartedly and selflessly, but ended up a joke!
As a result, not only was she getting weaker and weaker over time, her mental health was also steadily declining into a zone of self-hypnosis. In the two years that the kids survived by themselves, Jin did the best that he could without making himself feel like struggling Jenna for causing his mind to ache due to her action. No matter what he said or do, Jenna JUST. DOES. NOT. LISTEN! She wasn't eating as she should, she wasn't resting when she has to, and oh god, Jin just wants to knock the girl out. But since Jin can't do that, either, he just leaves her alone to her action most of the times while he did his things.
