"Do you think that I will still live longer?" Hyeongjun asked his best friend Wayen.

"What thㅡ"

"Do you think Mom and Dad will find a donor?"

"Stop Hyeongjun. You will live longer. They are doing their best to get you a donor."

"Noona, thank you for coming into my life." he whispered.

"Is that your last farewell?" Wayen jokingly asked.

"Hmmm maybe? But seriously, thank you from the bottom of my heart."

"You know that I will do everything for you, right?" he nodded as an answer. "You're too young to die, Hyeongjun. I know you have dreams to achieve."

"Promise me that you will fight. You will live longer and become an idol."

"Woah, I feel like this is your last farewell. Are you gonna donate your heart for me?" The boy asked her jokingly.

"If you will live longer. Why would it not? Promise me that, okay?"

"Promise."

"Mr. and Mrs. Song, we need a heart donor for Hyeongjun as soon as possible." The doctor said, "If he still can't find a donor, he might die."

"Yes, we know that Doctor Han. We will inform you if we have already found a donor." Mrs. Song said and the doctor excused himself and left.

"What should we do now? We still can't find a donor for Hyeongjun. I don't want my son to die." Mrs. Son uttered.

"We don't want that to happen. I will do everything just to save our son. Okay?"

"What's wrong Mrs. Song?" Wayen asked, carrying a flower and a basket of fruits.

"The doctor said, we need to find a donor as soon as possible. If not, he might die."

"The problem was we couldn't find any. He is my one and only son. I don't want to lose him."

"Don't worry about that Mr. and Mrs. Song, I know someone who's willing to donate a heart for Hyeongjun." She said with a smile on her face.

Hyeongjun was sleeping when someone knocked on his hospital room. He opened my eyes and saw Wayen. She is smiling at him and waving her hand.

"Can I come in?" She asked. He nodded and she closed the door.

"What are you doing here? It is already midnight, you know that the visiting time is over?"

"I just want to visit you. Is that bad?"

"It's not but it's midnight. You have school tomorrow. Did your parents know that you're here? What if something happens to you?!" Hyeongjun scolded her.

"I am older than you, kid."

"Still, you're a girl. It's dangerous to go outside at this time." While scolding her, Hyeongjun noticed that she's wearing a white dress, which Wayen never dared to wear.

"Noona, why are you wearing white dress?" The boy l asked out of curiosity. But Wayen just smiled at him, obviously ignoring his question.

"Oh, it's already time. Goodbye my dearest best friend. Take care of yourself, okay? I love you." After she bid her goodbye, Wayen kissed Hyeongjun's forehead. He lifted his hand to stop her but she vanished like a bubble.

Hyeongjun suddenly woke up and the sun was already rising. The first thing he did was to find his best friend. He looked to his surroundings but there's no sign of his Noona.

"Mom? Where's Wayen Noona?"

"Honey, Wayen said she needs to go somewhere." His Mom explained and gave him a ressured smile.

After spending another month in the hospital, he was finally discharged. He really missed his Wayen Noona. It's been a month and half since she left and went somewhere. That night was the last time they spoke to each other.

While resting in his room, he saw a pink envelope on top of his study table. "What's these?" It's a letter for him. Out of curiosity he opened the letter.

Dearest Song Hyeongjun,

First of all, I apologize for not telling you the truth. I know you won't agree when you find out that I gave my heart so you could live.I can't bear to see you suffer anymore.Don't blame yourself or your parents, it was my decision.I want you to be strong in your second life and fulfill your dream.You will always remember that I am not lost, I am just here by your side to guide you on your journey.

Sincerely,

Wayen.
