[Flashback: 7 years ago]

Hanbin: Can the two of you just quit bickering and look at the camera?

Chanwoo: Aish hyung, your boyfriend won't cooperate.

Yunhyeong: Can you at least pose and smile decently? 

Chanwoo: Hanbin hyung, why are you dating him again?

Hanbin swears to himself he's about done with them. 

Hanbin: Okay look at me now.

The brothers did and the camera snapped. 

Yunhyeong: You look ugly here.

Chanwoo: You too... but uglier.

Hanbin: You both look so stiffed. But you two look alike and duh you're brothers.

Yunhyeong: Kim Hanbin did you just call us ugly? You dare disrespect my handsome face?!

Hanbin only responded to him by showing his tongue before he ran away. Chanwoo looked at the 2; he wished to have a relationship like that too. 

[Present time]

Chanwoo went to get his hyung's letter to take Bin off his mind even for a bit. And get going on finishing all the letters he has. After all, its the notebook he is most curious of.

Chanu,

My annoying dongsaeng, thank you for coming back. You know that is what I said the moment you opened your eyes again and looked for me. I want to say sorry for not allowing anyone to mention 'him'. When you already cannot remember anything about 'him'. It must have been cruel of me, I know. If I could only turn back time... Maybe you should have been happier. 

If a time will come that you'll hate me, I will understand but before that don't hate yourself. Chanwoo, you know how precious you are to me. 

[Chanwoo tries not to cry knowing his brother might have a hard time putting his feelings into words]
