Kiss Shite Sugar-kun!
Might be reading too much into this... But this story especially felt real to me. The author has a way of creating characters that portray emotions so deeply. This manga really spoke to me. I thought it would be about some regular high school love that ends in fluff and has a clear antagonist. But it was an internal struggle instead. I understood the feeling of fear that the characters felt in not being good enough and not understanding the feelings enough. The feeling in which it was as if they were missing something important. Of also not being able to understand the world around them and then coming to the sudden realization. The scene where the bottom bursts into tears and the one last scene for his performance were especially moving. This isn't just some weird story as other comments may suppose. Beautifully portrayed.
