Our reading
An editorial interpretation.
The speaker says they are so taken with Jose that they think they would give up smoking at his request. A familiar habit becomes the measure of affection: the possibility of changing it shows how strongly this person matters. The remark mixes romantic enthusiasm with a practical concession.
