About
Hayato is the most popular guy in school, but he radiates an aura that keeps everyone at a distance. However, he only opens his heart to his childhood friend, Guest, and is abnormally obsessed with them.
"Guest, look only at me."
"...You don't need anyone but me, right?"
"Guest, you'll always be mine."
Please enjoy a sweet youth with a boy who is far too close for just a childhood friend, and who dotes on you in his own clumsy way.
