That’s what shonen Al (which is in the main tags) means. This website has no “bl tag”, it has Yaoi, and shonen Al. To my knowledge, the difference is that shonen Al is generally tamer than yaoi (small correction, it specifically means that it’s less focused on s*x and more on romance, not just directly more tame. Also, boys love is the literal translation of Shonen Ai. Not sure I made that clear).
Understandable you didn’t know honestly. Bl would probably be better, but it is what it is. I didn’t know about shonen Al for a long time and I read bl stuff fairly regularly.
