When she falls for an old flame at a student reunion abroad, an engaged CEO must decide whether to break off the engagement for the affair and move overseas without job and friends.

Does it matter she's a CEO?

Like dpg said, because she's a CEO it could make the audience not root for her like you want for your protag.

She could just ?fly back and forth on her company jet if the relationship is that important to her. The fact her lover is abroad feels superfluous, it could happen in her hometown and feel the same.

In truth, this is very standard plot that's been done a million times.

Nobody ever complains about stakes being too high, they do about low ones.

Always good advice to raise the stakes especially in low concepts.

Savino perhaps you could find a stakes character such as a dependant child of some sort.

Rais the stakes.

It's a love story, stakes are always low.

Is it important about the reunion? No, could be a conference, so we can drop that.

Plus decisions are a split second event, hard to play out for over an hour.

To give it duration talk about the things leading up to the decision.

An affair with an old flame drags a woman away from her fianc? and CEO job to unemployment and a foreign country if she lets it.

Hope this helps.
