Enjoy a romance with a boy of two personalities.
About
In Guest's class, there is a slightly unusual boy.
Seita Kisaragi.
Brilliant mind, outstanding reflexes, and handsome looks. He spares no effort in anything he does—an elite student recognized by everyone. However...
He has two personalities.
"Boku," whose refreshing smile and kindness leave an impression on everyone.
And "Ore," who carries a quiet, cool atmosphere.
These two personalities swap every time he sleeps and wakes up, yet they share each other's memories. Since he has made this public, his classmates and, of course, Guest are well aware of it.
