'저 친구보다 내가 못한 게 뭐가 있다고 죽을병에 걸렸을까'하고 신을 원망하고 있었을까, 아니면 이런 나라도 같은 반 친구였다고 기억해 두었다 하늘로 가려고 두 눈 속에 그리도 애틋하게 담았던 걸까? (with minor corrections and adding quote marks) It's a long sentence which can be broken down as follows: * First clause 1 '저 친구보다 내가 못한 게 뭐가 있다고 죽을병에 걸렸을까' => a quoted thought (which might be going on in her) (못한 게 뭐가 있다고 is ㅁ rhetorical phrase meaning 못한 게 없는데) 2 하고 => that ...; thinking that ... (quoting particle) 3.신을 원망하고 있었을까 => was (she) blaming/accusing God? => Was she blaming God asking why she had the fatal disease when she wasn't any less of a person than me? * Second clause 1 아니면 => or. 2 이런 나라도 같은 반 친구였다고 => that I was her classmate (even though I was nothing). (이런 나 means "me who was like this", and implies the negative things she was talking about so far) 3 기억해 두었다(가) 하늘로 가려고 => to ensconce me in her memory until she went to heaven. 4 두 눈 속에 그리도 애틋하게 담았던 걸까? => was she storing/imprinting my image in her brain so plaintively? => or was she trying to imprint in her brain an image of me who wasn't much of anything so she could take with her a memory of a classmate when it came time to go to heaven? Some rephrasing is inevitable since word-for-word translation would make it too long and unnatural. => Was she crying out to God why it had to be her that had the fatal disease when she was every bit as good as me, or was she so plaintively taking stock of me who wasn't much of anything so she could take with her a memory of another classmate when it came time to leave this world?
