Yes it's bad!!
The Point of Lover is oh shit I want to be with this person forever!! "can we always be this close?" is the question asked by someone used to it always going wrong and is braced for a crash, a male reassuring voice destroys this vulnerability

exemplified by him belting back "i'll save you a seat" - the softness was what made it! 'Saving someone a seat' is innately vulnerable! they might not join you, the voice of Lover risking it is a sign of love - him immediately reassuring her gets rid of the weight of risk!

Similar she names all her flaws and self doubts and doesn't have him/tell him to answer her, as she does in Love Story, Wildest Dreams etc, "i'm highly suspicious" "swear to be over dramatic and true" has emotional weight bc this anxiety is not soothed by him
