Most saddest phrases?

Heart wrenching words I have heard.

One being from Ten Years I Loved You the Most: (It’ll make sense and hit hard after reading) “Let’s go home after school today.”

Stupid guy, how can he hurt MC…I will never forget. I even cried at the stupid guy’s final letter before he followed MC years later.

Another one: “I know you don’t love me, but if I wait, will you love me one day?” (Not from anything I think, but it came to mind and I felt sad.)
