What happened to Lin Shun and Zhiyu’s mother?

Meizhen gets into trouble after a confrontation with her pseudonym Na Ok-hee (hereinafter referred to as Ok-hee for ease of understanding).Meanwhile, Jiaying finishes her skin care and realizes that she has missed 12 missed calls from Meizhen.Mi-jin's last message said that Ga-young should call the police if she couldn't be reached, but Ga-young immediately informed Ji-woo because he acted quickly and cared deeply about her friend.

Meanwhile, Ok-hee chases Meizhen through the forest and eventually suffers a nervous breakdown.I think she feels guilty about the real Lim Soon's death because she hallucinated that Meizhen was the real Lim Soon.Eventually, Mi-jin manages to inject Ok-hee with a sedative (the same fentanyl Ok-hee used on her victims) and knock her unconscious.But Meizhen herself was injured.

When Zhiyu arrived, he didn't know where to go and only found Meizhen's father's mobile phone.When Zhiyu tries to find Meizhen, he encounters the orange cat that started it all.Zhiyu remembers that Meizhen once told him that cats always repay what is given to them, so he follows the cat.

The next morning, the cat brought Zhiyu to Lin Shun.Zhiyu found Lin Shun unconscious and picked her up in disbelief.He then told everyone what happened and soon, as he kept saying, several bodies were dug up in the area.Eventually, two bodies were found: Zhiyu's mother and the real Lin Shun.Zhiyu breaks down and realizes that he never had the chance to reunite with his mother.

Meanwhile, Meizhen and her father were taken to the hospital for treatment.She could only look at her father from a distance because she turned into Lin Shun.At night, even though the culprit had been caught, it took her longer to recover, which meant either this was permanent or there was something else she needed to do for her aunt.

It seems Ok-hee killed Lin Soon because she found out that Lin Soon stole money and pretended to be someone else.She tries to tell Baek Cheol-kyu, but we know how that turns out.Zhiyu’s mother saw Okxi dragging Lin Shun’s body.Ok-hee then takes a job where Ji-woo's mother works to see if she will tell what she saw.Ultimately, Zhiyu's mother tried to do the right thing; this led to her eventual death.Before she died, she had begged Ok-hee to spare her life for Zhi-woo's sake, and Ok-hee now told the grown-up Zhi-woo, hoping to anger him.However, Zhiyu never showed any signs of pain in her presence.

He then talks to the detective who is now an intern in the office and basically tells him that he did his best and he doesn't blame him.He also told the lead detective, who had dementia, that they had found the child's mother, which excited him to run to tell the boy.This is a rather sad arrangement.Meanwhile, Meizhen thinks she is the cause of the chaos, and Jiaying comforts her.

Why did Meizhen break up with Zhiyu?

In the evening, after the whole incident was over, Zhiyu showed up at Meizhen's doorstep.While this is usually a happy sight, this time it was bleak as they all learned of the death of a close family member.But more importantly, Zhiyu already knew about Meizhen's situation because he saw the changes in her when he went to find her that day.He's frustrated that Meizhen never told him, but Meizhen tells him that it's not about trust, but that it's hard for her to share something she doesn't like about herself.Finally, she told him that they should break up because she didn't want him to be burdened with her problems and that she should take responsibility for her actions.She also tells him that if she tells him the truth, she will never get the chance to work with him, and that this opportunity only comes when she becomes an old woman.

On the other hand, Lin Shun and Gao Yuan gave statements on the case, and they confirmed each other very well.That made another prosecutor suspicious.Also, Lin Soon turns out to have a stolen identity, so that's a bigger problem.However, Ji-woo protects Meizhen's safety by telling another prosecutor that if she reveals the truth about Im-soon's stolen identity, then he will reveal the fact that Im-soon found the criminal and solved the case on his own.When he learns that Ji-woo will be transferred back to Seoul, his boss gives in, much to his delight.

At the end of episode 15, Mi-jin’s mother can’t believe her sister was murdered.When Meizhen came to talk to her as Lin Shun, she apologized for not recognizing her and hugged her tightly, promising never to let her go again.However, when the sun goes down, Meizhen changes back to her original self, and her father sees it.When Meizhen's mother released her tight hug, she was shocked to see Meizhen instead of her sister Lin Shun, who she thought was dead.
