I’m sure sb would adore bg in any hairstyle 😩 He recognizes the unique charm that comes with both long and short hair. Long hair enhances the elegance of bg’s features, and I feel like it also influences his persona and attitude. He appears more graceful and sophisticated with long hair. And omg yes, sb used to love playing with bg’s hair when it was longer! I think he admires how well bg can pull off styles that he might not consider for himself, finding a certain satisfaction in seeing it on him.
That said, it’s undoubtedly clear that sb has a strong preference for bg’s short hair. He’s been very vocal about it, and when bg had gotten a haircut for the award show in Jakarta last year, sb literally couldn’t stop staring. He couldn’t hold back from complimenting bg, saying he “looked like his prime today,” which made bg so flustered that it left him speechless.
Since bg has such androgynous features, long hair can make him appear more feminine. I feel like that’s something hetero guys would find appealing because it aligns with their visual attraction to females. sb loves bg for who he is as a male. I think he feels that bg doesn't need long hair to be pretty and he actually seems to appreciate the boyish charm that short hair brings out in bg more.
