Is this yaoi or shonen ai? why does it have both tags? can someone tell me? ._.

yeah it is a little confusing there are actually several books like this
(●￣(ｴ)￣●)

It happens at times when the first chapters don't mention s3x or anything like that, it gets rated as shounen-ai. Then it changes to yaoi ones there's a making love scene.

It's more shounen ai. They literally have one panel in the entire manga that shows them sleeping together.

Thank you :0
