how can i make my kick have the player and a optional reason?

I want my kick command to be able to kick the said player and at the same time have an option to be able to say a reason as well but, I cant seem to be able to get the player and the reason separately. Here is my script:

function Run(args)
	script.Parent.Parent.exe.SE:FireServer("",args)
end

game:GetService("UserInputService").InputBegan:Connect(function(e,gpe)
	if e.UserInputType == Enum.UserInputType.Keyboard then
		if e.KeyCode == Enum.KeyCode.Return then
			local text = script.Parent.Text
			local txt = script.Parent
			if string.find(text:sub(1, 4), "kick") and string.find(text:sub(6, #text), ".+") then
				txt.Text = ''
				local user = text:sub(6, #text)
				local reason = "No Reason Given."
				if string.find(text:sub((6 + #user), #text), ".+") then
					reason = text:sub((6 + #user), #text)
				end
				if user:lower() == "others" then
					for _,plrs in pairs(game.Players:GetChildren()) do
						if plrs.Name ~= game.Players.LocalPlayer.Name then
							Run("game.Players." .. plrs.Name ..":Kick('" .. reason .. "')")
						end
					end
				elseif user:lower() == "all" then
					for _,plrs in pairs(game.Players:GetChildren()) do
						Run("game.Players." .. plrs.Name ..":Kick('" .. reason .. "')")
					end
				end
				for _,plr in pairs(game.Players:GetChildren()) do
					if (plr.Name:lower():sub(1,#user) == user) then
						Run("game.Players." .. plr.Name ..":Kick('" .. reason .. "')")
					end
				end
			end
		end
	end
end)

i have used prints in parts of the script and they have been removed, the result I'm getting is the user and reason together when I try to print local user. Please someone help me because I don't know what to do at this point.

Ive got a working one thx to widesteal, if you wanna check my version out here it is:

function Run(args)
	script.Parent.Parent.exe.SE:FireServer("",args)
end

game:GetService("UserInputService").InputBegan:Connect(function(e,gpe)
	if e.UserInputType == Enum.UserInputType.Keyboard then
		if e.KeyCode == Enum.KeyCode.Return then
			local text = script.Parent.Text
			local txt = script.Parent
			if string.find(text:sub(1, 4), "kick") and string.split(text, " ")[2] then
				txt.Text = ''
				local user = string.split(text, " ")[2]
				local reason = "No Reason Given."
				if string.split(text, " ")[3] then
					local rTable = {}
					reason = ""
					for i = 3, #string.split(text, " ") do
						table.insert(rTable, (#rTable + 1), string.split(text, " ")[i])
					end
					reason = table.concat(rTable, " ")
				end
				if user:lower() == "others" then
					for _,plrs in pairs(game.Players:GetChildren()) do
						if plrs.Name ~= game.Players.LocalPlayer.Name then
							Run("game.Players." .. plrs.Name ..":Kick('" .. reason .. "')")
						end
					end
				elseif user:lower() == "all" then
					for _,plrs in pairs(game.Players:GetChildren()) do
						Run("game.Players." .. plrs.Name ..":Kick('" .. reason .. "')")
					end
				end
				for _,plr in pairs(game.Players:GetChildren()) do
					if (plr.Name:lower():sub(1,#user) == user) then
						Run("game.Players." .. plr.Name ..":Kick('" .. reason .. "')")
					end
				end
			end
		end
	end
end)

I use a table to put the spaces back together so the words are seperated
