Double Date

CodeChefOpen on judge ↗

Chef and Chefina are in love. But not with each other. Chef loves Chefu, and Chefina Cheffa. They're planning a double date but Chef and Chefina like it old school so they have the date and venue written on a note that they want to pass it over to their partners Chefu and Cheffa. The only problem is that there is a solid wall in between. You're given the coordinates of Chef and Chefina (point $P$)
