How Do I Gracefully Exit a Job I Joined for Just 5 Days Without Hurting My Career?

Hi all, I have made a terrible mistake and need advice from all of you.

Background of the Situation

I am a software engineer and have received offers from two banks (MNCs). Bank A provided a joining date in May 2017 but suddenly changed it as the Pre-Employment Screening (PES) was not completed. I panicked and accepted Bank B's offer. They provided an earlier joining date, so I joined there. The next day after joining Bank B, I received a joining confirmation from Bank A. Since I preferred Bank A, I made an excuse to Bank B, took a 5-day leave, and joined Bank A.

Current Dilemma

Now, both banks have the same banking partner where they credit salaries. This situation is going to create a problem. I have decided to resign from Bank B and continue with Bank A, where I originally joined, as the salary account is already opened there to avoid any issues.

Request for Advice

Please advise on how I can smoothly exit from Bank B, where I only worked for 5 days, without impacting my job history. I do not want Bank B to find out about this mistake.

Thank you for your help.
