One of the best BL series I've seen. So many little things done right. Really cute actors accurately cast. Interesting and very sophisticated dialog. The story takes place in an all boys school but the costuming manages to keep the scenes fresh with minor adjustments to the uniforms. Music that enhances the story. Gorgeous cinematography. Very interesting personalities of the characters. The pacing is excellent as we move along gently with the characters as they change and mature. I could go on but you get the picture. If you haven't started it, yet don't hesitate. You will fall in love with all of them.

Here's a thought. They were seniors in high school. Why not a second season with their experiences at a university?
