Whats the rule that makes "please" pronounced the same as "pleas"?

There's no rule.
Pleas is spelled <pleas> because it's the plural of pleas.
Back in the day (circa 1300), it was written <plesen>.
Words are pronounced the way that they're pronounced.
Whence the <ea> I cannot say but some other words that were spelled <ai> in French are spelled <ea> in English: aise → ease, graisse → grease, fait → feat.
Please is an anglicization of the French word plaisir.

While you may reasonably ask why words are spelled the way they're spelled, it makes no sense to ask why they're pronounced the way they're pronounced.
What's (not “whats”) the rule?
You'll usually find your answer there.
