Seduced by My Best Friend

Shion and Rui are college guys and best friends who spend their free time picking up women together — until a mysterious drug handed to Shion by a stranger completely upends that arrangement. He wakes up the next morning in a woman's body, and before he can figure out what happened, Rui meets his transformed friend without recognizing him. Things get complicated fast. The series is an 8-episode ONA from Elias, with each episode running around 6 minutes, so the whole thing goes by quickly. It leans into the awkward comedy of Shion navigating a body that isn't his, while also being honest that this is Boys Love with explicit content — don't go in expecting anything tame. What makes it interesting is that the gender-swap isn't just a gimmick. It genuinely reshapes how these two interact and what their friendship means. If you've seen Kashimashi: Girl Meets Girl or Kämpfer and liked the gender transformation angle, this covers similar territory but filters it through a Boys Love lens, which gives it a different emotional texture. Fans of that niche will probably find the premise clicks in a way that feels fresh. It's a short commitment, the setup is specific enough to hook you in the first episode, and it does not try to be something it isn't.
