• 惜しいおしいJLPT N2approx.Common

  あなたほどの才能さいのうの持ち主もちぬしが世間せけんに知しられずにいるのは惜おしいことです。↗

  It is a pity that a man of your ability should remain unknown to the world.
• 不本意ふほんいCommon
  na-adjective, nounNot really the word for 'disappointing' in ordinary use; it means reluctant, unwilling, or against one's wishes, as in doing something reluctantly or ending up with an unwanted result. Treat it chiefly as 'reluctant' or 'unwilling'.
  彼女かのじょは不本意ふほんいながらもそうした。↗

  She did it against her will.

Use 残念 for general regret over an unfortunate outcome, 「惜しい」 when something fell just short or was wasted, and 不本意 mainly for reluctance or acting against one's wishes rather than for 'disappointing'.
