There's no rule.
Back in the day (circa 1300), it was written <plesen>.
Pleas is spelled <pleas> because it's the plural of pleas.
Please is an anglicization of the French word plaisir.

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.
