Hi Bye, Mama!

Cho Gang-hwa is shaken by the sight of Yu-ri, who's got 49 days to find her rightful place. What's more, Cho Seo-woo has gone missing.

Gang-hwa isn't sure how to reveal that he got remarried. Wanting to protect Seo-woo from lurking ghosts, Yu-ri eyes an opening at the preschool.

Gang-hwa worries when Oh Min-jeong notices that Yu-ri looks familiar. At her new job at the preschool, Yu-ri learns the child ghost's secret.

Yu-ri's human form causes a stir with the ghosts at the columbarium. Yu-ri slips up in front of Gang-hwa and Min-jeong at the preschool.

Min-jeong wakes up with a mysterious face wound, and contemplates a big decision. Meanwhile, Gang-hwa faces disciplinary action at the hospital.

Yu-ri meets Min-jeong about an opportunity. While fulfilling a wish from Jang Pil-seung's family, Yu-ri finds herself in an awkward position.

Yu-ri can't help but notice a ghost and his daughter's unfortunate circumstances, and crosses paths with someone who shouldn't see her.

Determined to kick out an unwanted ghost from Seo-woo's home, Yu-ri starts babysitting her. Gang-hwa makes an upsetting blunder.

With half her allotted days already gone, Yu-ri focuses on taking care of Seo-woo — and Min-jeong. Elsewhere, Gang-hwa and Jeon Eun-suk meet again.

The arrival of an unwelcome guest sets Ms. Mi-dong on edge. Yu-ri, Min-jeong and Go Hyeon-jeong have had enough of the preschool's bullying moms.
