Boy A (a random background character from episode 3 [14:47] of My dress up Darling)

Browsing on reels on fb when I stumbled upon a clip of my dress-up darling, at episode 3 where they're talking about a hentai manga scene(?) And the line of adults the passed by let out a gasp when they heard the topic they're talking (gojo and Marin I mean), anyway there's another background character girl infront but the one that caught my attention is the brown haired guy leaning on the wall.
