Multiple values saved using a single data store, Possible? (FE)

Hi guys, I'm trying to save a leaderstats with 2 values, here's my simple code:

ds = game:GetService("DataStoreService"):GetDataStore("DsName")  
PlayerStats = game:GetService("ServerStorage"):WaitForChild("PlayerStats") 

--Creating a leaderboard--
game.Players.PlayerAdded:connect(function(player)
	local key = player.UserId
	
	local playerfolder = Instance.new("Folder",player)      
	playerfolder.Name = "leaderstats"						
	
	local kill = Instance.new("IntValue", playerfolder)
	kill.Name = "kills"
	
	local point = Instance.new("IntValue", playerfolder)
	point.Name = "points"
	
	local asset = ds:GetAsync(key)      					

	if asset then
		kill.Value = asset[1]     --Error appear at this line.
		point.Value = asset[2]
		
	else
		local newleaderstats = {kill.Value, point.Value}
		ds:SetAsync(key, newleaderstats)
	end
end)

An error: "ServerScriptService.Script:51: attempt to index local 'asset' (a number value)" appeared at line 20 of my code. Was the error due to my datastore having only a single int value hence local asset is deemed as a variable and not an array? any idea what's wrong with it?
