You’re Isagi

Kaiser and Isagi are in a complicated relationship, a distorted relationship…They are both lovers and rivals…

While Kaiser was looking at the iPad in his private room . Kaiser frowned when he saw the words “Rinsagi”…

Kaiser’s hand tightened around the iPad. Kaiser only showed jealousy when he was alone, but he rarely showed jealousy in front of Isagi and Kaiser’s stubborn personality…

Isagi's side is not doing any better as he catches the words "Kainess" on the iPad…
