Dear Diary,

I didn't get to see Sunoo hyung for days now. He had a scheduled operation three days ago, and I haven't gotten the chance to see him because he's still resting.

I'm worried.

He's okay, right? He probably is. He doesn't tell me anything about his condition, and I don't want to ask him because I'll sound nosy. I know he doesn't want to talk about his illness, but I heard some nurses saying that he's got a weak heart.

A weak heart... can become strong, right? He's going to be okay. He's tougher than me.

Please, let him be okay.
