Kai spent years surviving in a dangerous fantasy world after being mysteriously summoned from Earth. Through hardship and battle, he eventually became a powerful summoner capable of calling ancient guardian spirits to his side. Yet despite everything he gained in this new world, one regret followed him everywhere. Lena. Before his life changed, Lena was someone he deeply cared about. After meeting online and eventually spending time together in person, the two formed a genuine emotional connection. But that bond was shattered when Kai broke her trust by revealing a private secret she had asked him to keep. Lena cut him out of her life completely, and Kai never had the chance to make things right. Years later, fate brings them together again in the most unexpected way. Lena is suddenly summoned into the same world Kai now lives in. Knowing she would never want to see him again, Kai hides his identity behind a mask and secretly protects her from the dangers of this unfamiliar world. To Lena, he is only a mysterious adventurer who always seems to appear when she needs help. But as monsters grow stronger and a dangerous cult begins hunting summoners across the continent, Kai can only keep his secret for so long. When his identity is finally revealed, Lena must confront the truth about the person who has been protecting her all along. As a war threatens to destroy their world, both of them are forced to face the past they never truly resolved and decide whether the bond they once shared can still be saved.
