Eiser doesnt want to promise anything rn coz he wants serena to not be bound by a promise and stop enjoying life. He wants her to find what makes her happy and if by chance that happiness is something other than being with Eiser then she shouldn't feel forced or guilty to fulfill that promise they made.
Serena on the other hand wants that promise to be the motivating factor for their upcoming struggles so that they can go through it and whenever they feel like giving up, that promise to be together in the future will encourage them to not give up. She doesn't see it as a burden that should be fulfilled but rather an end goal that they need to work through to achieve.
I get Eiser's feelings and how he's looking out for Serena but i cant help but take serena's side because even if in Eiser's mind he's giving serena an option tp choose whatever she wants, he's forgetting the fact that he's doing the same for himself too, that is; for serena it might feel like Eiser is thinking abt a possibility where he mighy change his mind to not be with her and perhaps even find someone else.
I can understand both of their sides.
