ERC20 deployed & liquidity pair added but contract is receiving WETH?

Hey Everyone.

I developed my first smart contract. I deployed successfully onto Testnet. I have created a liquidity pool on Shushiswap testnet (Ropsten) I'm interacting with the pool fine. Although the first time I pulled ETH out of the liquidity pool Shushi asked me to add WETH to metamask. I did so, but I noticed my WETH balance was zero but my ETH balance went up to the correct amount. When I checked the ledger all transactions coming from Shushi are in WETH. Is this normal ? It seems that they are giving me WETH but it's automatically converting to ETH.

Here's a link to the tx

Here is my Smart contract

        _mint(msg.sender, 100000000000 * 10 ** 18);
    
    }

    function burn(uint256 amount) external {
        require(owner() == _msgSender(), "Ownable: caller is not the owner");
        _burn(msg.sender, amount);
        
    }
}
