hikaru goes into the mountains and goes missing, only to turn up again a week later, but something is different about him and yoshiki senses that something is off. hikaru isn’t actually hikaru, but a ‘something’ taking the form of him, and ‘it’ has a one sided love for yoshiki, though it might be because the real hikaru already had those feelings. I really like this manga, but it makes my heart ache, I cannot wait for future updates!!
