she would have been around 11/12 when he did, so maybe a disappeared/reconnected later? or not that! i think a bff might be fun, where they both decided their friendship was too valuable to waste on their libido (even though they spend most of their time with each other and it would make a lot of sense)? or the cliche ex-line, where it was super recent and they're in an awkward "can we still be friends?" stage? or it was a long time ago, and they reconnected recently?
