Im a bl fan and he is not (honestly it kinda like free without the abs), it about the love of skateboarding, friendship, some angst (but what do you except, its a sports manga), and wholesome shit. Anyway like most sports the prime focus is the love and passion toward the sport unless highlight otherwise.

i forgot which episode when it happened but at one point langas mother asks him if he likes the person hes talking abt (using the romantic sort of 'like' in japanese
and theyre talking about reki) and langa blushes and says 'Yeah.' So it's either he really does love him or there was some sort of mistake on langa's part. The only logical explanation is that langa is not too familiar with japanese so he might've gotten it wrong but idk if bones thought of that..

and just the subtext of the show and the official art show that they like each other. skating is a metaphor for love and they realize they can only do it together or its no fun, they are each other's happiness. (also when Reki and Langa look at each other in later episodes their eyes have the same look as in episode 6 when they're practicing flirting)
yo, idk who confirmed it or if this shit is official (likely not, for now?) but google "is Langa a gay character" and it pops up that he is, according to LGBT Wikia Fandom and that his crush is Reki. I know this story mad queerbaiting but Imma need some real answers on is Langa gay....
