okay it seems like a lot of people skipped to see the ending and were trying to interpret based just on the images so here’s what they actually say in the ending: (*SPOILER**)
Yoon (black hair guy) basically writes a letter that says he continued to research to cure(?) the blonde guy until Yoon was 50 years old, but he himself failed. He would let future generations continue the research, but he decided to go into deep sleep next to the blonde haired guy as a 50 yo. The letter tells Haejin (blonde hair) if he still wants to be with Yoon who is older than him when Haejin wakes up, then Haejin can go to the pod and say something because the pod is voice-activated to open in Haejin’s voice. We see that Haejin does go and say to wake up, which means technically they’ll end up together!
