Park Hye Min was busy on her phone so she didn't realize that there was someone else in the room with her. So Song Ji Woo softly called Park Hye Min's name to grab her attention and to avoid scaring her.
Park Hye Min shouted in panic when she heard someone calling her name as she was alone in the room. She turned towards the sound and saw Song Ji Woo standing in her room, Ji Woo was a ghost so she looked translucent, Park Hye Min could see through her body.
Seeing this view, she shouted even more loudly and decided to run away from her room and ran towards the door. Song Ji Woo wished to tightly lock the door so that Park Hye Min couldn't escape and she could explain her situation.
As soon as Song Ji Woo wished so, the door really got locked from the outside, stopping Park Hye Min from escaping.
Song Ji Woo was surprised and realized this is a new power she got; whatever she would wish for would happen, she decided to check the extent of this power and its limitations later.
Park Hye Min panicked seeing the door locked and started shouting for help. She begged Song Ji Woo to not harm her and started crying.
"Park Hye Min please listen to me, I am not here to harm you, I am rather here to help you" Song Ji Woo tried to speak as softly as she could.
"What n...non..s..sense are you b...brew..wing? Wh..ho a..are you?" Park Hye Min asked with panic evident in her tone.
Song Ji Woo decided to cook up a story to avoid telling the truth, so she said "I am your fairy, I came here to take care of you."
"What? Fairy?" Park Hye Min asked. The word fairy calmed her a bit.
"Yes, I am a fairy, I am here to care for you. Please trust me, I am not here to harm you." Song Ji Woo gently smiled saying this.
Song Ji Woo was a beautiful person and with these gentle expressions and gentle voice she indeed looked like a fairy and easily fooled Park Hye Min into believing her.
Soon the door opened from the outside, Park Hae In and Shin Yoon Ah rushed into the room followed by other family members.
They all had worried expressions and they asked Park Hye Min why she was shouting.
Park Hye Min then turned towards Song Ji Woo. Ji Woo folded her hands and begged Park Hye Min to not tell them about her presence and she also told her that these people can't see her.
Looking at her family, Park Hye Min asked them if they can see anyone else in her room? Everyone was surprised by her question and said no. Then her father asked her with concern
"What happened dear, why you shouted and why are you asking if we can see someone here?"
Realizing that Song Ji Woo was telling the truth and no one could see her and seeing sad and scared expressions on Song Ji Woo's face, Park Hye Min decided to lie and give Song Ji Woo a chance to explain herself.
"Sorry dad, I was sleeping and I dreamt of seeing a ghost in my room so I shouted and therefore asked you if you can see someone in my room. It took me a few minutes to come back to reality, sorry everyone for the trouble" Park Hye Min apologized to everyone.
"But why was your door locked from the outside?" Park Hae In asked.
He was the first person to rush here and saw the door was locked from outside and he was the one to unlock it.
Song Ji Woo saw a boy of 4 years old in the room and wished to enter his body.
Then she transported into his body and said, "sorry uncle while playing around, I got confused and instead of locking some other door I locked this one"
Understanding that the boy is small and can make such mistakes, everyone let go of this door incident and Song Ji Woo came quickly out of his body. Park Hye Min was focussed on her brother and didn't see what Song Ji Woo did and therefore didn't realize that Ji Woo just entered her nephew's body.
Park Hye Min too thought the boy locked it by mistake.
Song Ji Woo was surprised that this plan worked, although she wished for it, she was not sure if it would work. She was happy with this another new power she got.
Saying goodnight and asking Park Hye Min to take care of herself, everyone left.
After all left, Park Hye Min locked the door and carefully approached Song Ji Woo and asked "Who are you? What is happening?"
Song Ji Woo asked Park Hye Min to sit on the couch and she sat there with her.
Park Hye Min was now feeling less scared of Song Ji Woo and sat with her.
"My name is Song Ji Woo, you can call me Ji Woo. I am your fairy; I came here to take care of you."
"But why? Why do you need to take care of me? And do fairies really exist?" Park Hye Min asked all the questions she had in her mind.
"I am also not sure why I am here; I am your fairy and I am supposed to protect you secretly but not sure what happened that I am visible to you" Song Ji Woo easily lied.
She continued "I need to take care of you because that is my duty. And yes, fairies do exist, every person has a fairy to protect them but they are never visible, I think in this phase of your life you need your fairy to be with you and maybe that's why you can see me" Song Ji Woo cooked any story that came to her mind and seeing Park Hye Min's expressions, she understood that Park Hye Min was believing her.
