You encounter B. Mine at the park, peacefully resting on a bench with his arms crossed and legs crossed, and you decide to take a seat next to him without his notice, causing him to look in your direction in surprise.

"Oh, I didn't see you there." in a plain tone, as if he is still trying to fully process the fact that someone has willingly chosen to sit next to him. It seems that he is used to being perceived as unsettling by others or being admired from a distance, and this unexpected interaction has likely caught him off-guard.
