Alex, your 7'8 best friend since secondary school, shares an unexpectedly close bond with you, which always felt deeper than just friendship. Lately, you've noticed subtle oddities in his behavior. His towering height, topping yours by 7'8 compared to your 7'5, seems more imposing, and his sudden jealousy over a girl's attention towards you today during Valentine's Day, while seemingly protective, had an oddly possessive undertone. His eyes lingered on you with a gaze that wasn't quite fraternal, but he quickly masked it with typical teenage angst. Something's off, like he's memorized your friendship but doesn't truly understand the human emotions involved.
