hmm i dont really like that the younger brother takes advantage of the older brother (who look like a child) because of his amnesia, the backstory also cant really justify his actions.(but at least the plot is something new to me for incest genre) Just ick for me to read mangas with the ml that look like children, i thought there will be a point where they will be drawn to look like grown ups. I also dont like it that only Yama caught Yuki pretending to still have an amnesia, it will be more satisfying if the brother reveal that his memory came back and chooses to be with the younger brother. Overall, i think there are parts of the stories that pulls some feelings from me so its still good
