This is how I see Eiser's standpoint as well. However, that's not what I think Serena wants. She wants Eiser to yearn for her, be desperate for her, make her his... all to himself alone.
And with the promise, idk if it's just me but maybe the phrase "promises are meant to be broken" is also in play here, given how Dia broke hers before and the betrayal he felt... maybe that's just me. ╮( ̄▽ ̄)╭
I’m not sure why ppl are upset…? if anything i interpreted Eiser words as him loving her so much to the point where he views Serena being married to him as a burden for HER and wants to grant her the freedom he feels she deserves, even if that means them not being married in the future..which is why he’s not making the promise or begging her to stay.
