As Charlie observed the interactions between Sam and Alice, a knowing smile played on his lips. From the moment he had first seen them together, Charlie had sensed an unspoken closeness between them, evidenced by their unconscious proximity and shared glances.
Charlie's gentle inquiry earlier about Alice being Sam's girlfriend had been deliberate, a subtle nudge to gauge their reaction and perhaps spark a deeper realization of their feelings. He had noticed how Sam's eyes lit up when Alice was mentioned, and how Alice's demeanor seemed to shift whenever Sam was near.
Now, as Charlie reflected on the unfolding dynamics, he felt a sense of satisfaction knowing that his simple tactic had succeeded in revealing something meaningful between Sam and Alice. The way they had blushed and exchanged looks spoke volumes, confirming what Charlie had suspected all along.
