Yoona: 12 years old.

Good morning, Appa! How is Heaven? Have you eaten breakfast? Yoona was the one who cooked breakfast today. I cooked hotdogs and eggs for

me and Krystal, while I cooked porridge for Umma. I fed Umma too, ‘cause she didn’t feel so well this morning. Did you know that Krystal has been

writing in this notebook a lot nowadays? She said that writing to you is fun. Krystal didn’t write any naughty things inside this notebook, didn’t she?

Keke~ She’s a good girl, Appa – your Yoona taught her well after all!

I went to Seohyun’s house with Krystal after I gave Umma her medicine and put her to sleep. Krystal played with Sulli, while me and Hyunnie went

to her room. I showed her some photos that I photoshopped myself. She looked so angelic as I showed her the pictures. Her eyes were twinkling

with amazement that I almost thought that her eyes were stars, keke~ I guess she found my Photoshop skills so good. Do you want to know the best

part? Seohyun and I had eye contact for like 10 seconds! I swear I saw love in her eyes! But then… Uncle Taeng appeared again and ruined the “mood”.

I saw her trying to take a peek at the door. I don’t know why, Appa, but I think she has a “Yoona detector” or something. She always knows when I’m

there at Hyunnie’s room. She never leaves us alone, and it annoys me so much, ‘cause I want to spend some time alone with Hyunnie. Thankfully,

Aunt Fany caught Uncle Taeng and scolded her for being so paranoid about me, Keke~ it just made me love Aunt Fany much more.

Appa, do you know the reason why I tried to learn Photoshop? It’s because of Krystal. I found a picture of us, where I was sitting on your lap, and

then found a picture of Krystal sitting happily on the couch. I photoshopped those pictures then combined it together, so that it shows Krystal was the

one happily sitting on your lap. I showed it to her. I was expecting her to be so happy, but she scared me when she looked up at me with tears in her

eyes. I cursed myself silently, thinking that I made her sad. She suddenly hugged me so tight while crying, saying thank you to me over and over again,

and telling me that I’m the best Unnie in the world. She was so happy with the photo that she made me hung one on her bedroom wall and stuck another

one on her lunchbox. I always saw her staring at that photo with the biggest smile on her face, and I can't help but smile too.

Appa, I’m sure you’ve noticed by now that your last birthday present for me was no longer around my neck. It’s the gold necklace with the “Y” letter

in a heart-shaped pendant. I never take that off since the moment you put it around my neck, ‘cause you told me that it represents Yuri appa’s love for

Yoona. You also gave a similar one to Umma years before, but hers is with letter “J”. You know… that necklace that you gave me means a lot to me,

Appa, I really treasure it a lot. Krystal always looked at it with a sad expression on her face. She knew that the necklaces were from you and was sad,

because Umma and I have the same kind of necklace, while she didn’t get to have one.

Umma tried buying her the same necklace with a letter “S”, but Krystal said she doesn’t want it, ‘cause it’s not from you. I couldn’t take seeing her sad

anymore, Appa, I felt really bad. So I decided to give her my necklace, even if it almost made me cry. I didn’t want to let go of it, Appa, ‘cause it’s very

dear to me, but I don’t want to see Krystal sad. Yoona will do anything just to see Krystal smile, even if it hurts me a lot. I know Appa wou
