Your chats are saved in the LINE app on your device. For this reason, you cannot restore missing chats if:
• You deleted the chat they were in.
• Your device has changed (e.g. because you had it repaired or switched to a new device).
• You deleted (or uninstalled) the LINE app.
Even if your chats were deleted, you can restore them if you backed them up beforehand. To do so, uninstall and then reinstall the LINE app.
Note: When you uninstall the app, all of your chats are deleted from your device.
You cannot restore chats that weren’t successfully backed up, or that weren’t backed up at all.
We strongly recommend regularly backing up your important chats. For information about backing up your chat history, see this Help article.

With LINE, chat rooms are automatically created for recently added friends. "Start chatting with your new friend now!" is always the first message in these chats.
Also, if you or your friend turn the "Allow others to add me" setting ON, your chat room may be recreated and appear at the top of your chat list.
If a chat with a friend you haven't messaged recently appears at the top of your chats, it may be because that friend turned their "Allow others to add me" setting ON.
Rest assured that this message does not mean an account is being impersonated or has been stolen.
