切ない

彼の切ない表情が忘れられない。

I can't forget the heartbroken look on his face.

遠く離れた恋人を思うと切なくなる。

Thinking of my faraway sweetheart makes my heart ache.

この曲のメロディーはどこか切ない。

There's something wistful about this song's melody.

板挟みになって切ない立場に置かれた。

Caught between the two sides, he was put in a painful position.

家族を養えない切ない胸の内を打ち明けた。

He confided the anguish of being unable to support his family.

頼る人もなく、切ない日々を送っていた。

With no one to turn to, she spent her days in hardship.
