Ka Shin Fu - Makoto Tateno Not better not worse than average yaoi manga. Story actually follows not only to Kaoru and Ryuugo but also to Shuu and Yuuichi. After first chapter in the second chapter has passed 20 years and yet Shuu and Yuuichi appearance has not changed more confusing is that Kaoru looks very similar to Shuu and Ryuugo and Yuuichi looks almost like twins.
