I read this manga about 2 years ago, I always find it difficult to bring up in conversation. I really enjoy stories that feature lgbtiq+ characters where their sexuality/gender isn't the main focus. While it is definitely a part of the main focus in this, it's not the only thing. There is one issue I should mention, Tetsuo's body, im mixed on it. On one hand they're sexualizing something that makes him dysphoric, on the other hand, trans people like him with larger chests do exist. I'll let you decide how you feel about. This manga has many twists and turns, I really hope that you'll give it a chance.
