Harbor, Port, Harbour
There's a tsunami coming and you want to be together with it by yourself (oneself) so you go to the harbor.
Picture the harbor. You're the only one there. The wind is whipping violently and all of the boats docked around you are being bounced around. You can see the tsunami rising out of the ocean and coming for you and the harbor.

As you look around at the harbor in your last moments you suddenly see someone in the water. It's こういち! He's sitting in an inner tube in the harbor waiting for the tsunami too.
Well this sucks. You wanted to enjoy being alone together with the tsunami and the harbor, but now こういち is here ruining your peace. He's floating around in the harbor like everything isn't about to be destroyed, sipping on a fancy drink in his inner tube.
