Stop loss on Covered Call questions

Hi there, need some help with the covered call option questions. Correct me if im wrong. Lets say today i buy 100 SMCI for $42 , and sell a Feb 14th $29 (ITM)Call option for $14 . At the expiation day, if the stock go below $29, if i set stop loss at $28.99, i will keep the premium, and the option will be worthless, and i won't lose on my long positions coz i exited with stop loss strategy. So i will never really lose? Thx for explanation!
