From the Eiffel tower they went to the love locked bridge and did the very cliche things that Alix hated and she took the lead eagerly.
After locking the padlock, she wrapped her hands around her neck and smiled.
"Now you are mine forever, this padlock proves it." She sealed the promise with a kiss.

In fact, the ring on her finger had more meaning than the padlock as it was a visible of their marital status to themselves and strangers.
Caishen just went along with her. He applied the anything to make my wife happy strategy and told his big brain to shut up and enjoy the kiss.
