      • EP1 - To My Ultimate Bias Stepbrother!

        Alba, who possesses memories of his past life, moves to the duke's household with his remarried mother. There, his new stepbrother turns out to be Orsis—the character he adored most in the otome game he played in his previous life. Though Alba rejoices at becoming family with his favorite character, he simultaneously recalls: In the game, it was because of his own excessive pampering by his stepfather that Orsis was plunged into tragedy.

      • EP2 - Laonen's Dysmagia Syndrome!

        Shaken by his encounter with Orsis, Alba suddenly collapses from a seizure. In this world, humans are born with magical power. However, Alba suffers from “Laonen's Dysmagia Syndrome,” which prevents him from controlling the release of his own magic. When he regains consciousness, he feels truly welcomed as family as his stepfather, Hals, and Orsis offer him warm words.

      • EP3 - My Brother is Too Cute!

        To prevent the relationship between Orsis and Hals from growing completely cold, Alba struggles to improve their bond. Through Alba's straightforward words and actions, Hals begins to reevaluate his relationship with Orsis...

      • EP4 - My Brother's Birthday Party!

        Just as Hals and Orsis' relationship was improving and things seemed to be going smoothly, they meet Orsis' grandparents at his birthday party. Facing harsh treatment from grandparents who don't think highly of Alba, Alba has another seizure...!?
