There appears to be 2 big problems with this logline.
The first is with the concept, as you said in an earlier post this is set in modern day as such most western audiences will likely not suspend their disbelief. Now day and age most adult women can and do marry whom ever they want with or without parental consent. As previously mentioned unless you specify a cultural background that provides such limitations on wedlock the concept will not work for most readers.
Secondly, as DPG mentioned, there is a problem with the plot changing the external goal will likely not work. What you can do is a change of approach to achieve the goal only this doesnt need to be in the logline.
Lastly the audience will care for the MC and want to see them do what they do if the stakes are high enough. Stakes increase interest in a story and in this instance the stakes just don't do that. This is only my opinion but it is an indication of what other people may think as well.
