• ストーキング
  noun, suru verbThe direct borrowing of English 'stalking,' for the sense of persistently following a person, as in harassment cases, rather than a single chase. It is less common than 追跡.

  That you should be stalking Hanako! You'd been quiet recently so I'd let my guard down.
• 追蹤ついしょう
