The other person cannot access your LINE data (such as your friends or chat history) and your account has not been stolen.
To prevent the same situation from occurring in the future, be sure to register your latest phone number to LINE if it changes.

We may be able to transfer some paid items after looking into the matter.
The following can be transferred:
• Stickers, themes, and emoji (including those received as gifts)
• Your purchase history of paid items, along with your Coin and LINE Point balances
