It isnt really "shonen" . But it just got "that feel" you know what i mean?? It's hard to explain. It's different than your typical yaoi. These authors have a really distinctive artstyle. If not very simplistic, its very stylized... Yknow, it's just those kind of BL where you dont mind any plot as long as the delivery, the atmosphere and the vibe is good. well, at least in my opinion.
