Helloooo! So an adult gay friend of mine's asking me to introduce him to some good yaoi (completed) and I'd love to hear your recommendations.
Please, no explicit rape depictions or non-con (due to my friend's history); unless given proper justice. One that has a good or compelling story (can be shounen-ai actually). I'd especially love to hear voices from those identifying as LGBTQI+ :)
