弟子の愛が重すぎて死ねない

Lucas, an elderly sorcerer, drew his last breath with his beloved pupil at his side... At least, that's what should have happened. When he wakes up, he finds himself in a room with a magic circle drawn on the floor... and his appearance transformed into that of a young boy! As if things couldn't get any more complicated, his dear pupil, Theo, who was only a child when he passed, appears before him as a grown man. Theo, driven to despair by his master's death, had used sorcery to bring him back to life. He's beyond thrilled to see his master alive once again, but something seems strange about him... Love knows no bounds when it comes to this obsessive, lovesick pupil and his beloved master! (Source: Renta!)
