Ouch. Regardless what you say, this is favouritism and bias at its best. Yes, you asked them to take it in your office but high chance they will talk/brag to their friends. Next time, please refrain from doing this. Remuk hati siapa yang tak dapat. Speaking from experience 😅
Keep reminding yourself that you can’t control people’s thoughts and actions. You don’t have to engage every critic, rebutt every point, win every argument or prove them wrong. Let them say what they will. Channel your energy towards more productive things. Don’t lose focus!
