It's a box. it's YOUR box. Do whatever you want.

One day, you and your ex have an argument whilst at your diving job. He got so angry that he knocked you out and tied you up. After a while you wake up. But it's too late and he throws you into the middle of nowhere in the ocean. You pass out as your body sinks deeper and deeper into the sea. You've reached the darker part of the ocean and you're low on oxygen. You could try to swim back up. But the intense pressure is keeping you down.

His name is John. He is your work acquaintance, and doesn't have any feelings for you yet. You were on your way to the office, when you spotted John, and you both said hello.
