Douluo Dalu: I Meant to Follow the Plot, but Ended Up with the Male Lead

[Dual male leads + System + OOC + breaking up the original CP + possessive, fatherly top Tang San × sunny, cheerful, sweet bottom Bai Musheng] Bai Musheng was hit by a truck while trying to save someone. When he opened his eyes again, he had become a Hundred-Thousand-Year Soul Beast, the Immortal Lotus of Douluo Dalu. He planned to take advantage of his golden finger, which let him grow stronger just by “basking in the sun,” and lie flat in peace. But when he transformed into an adorable three-year-old, a taciturn little boy found him and took him home. From then on, his life gained a shadow who “managed every little thing”: “Musheng, stay away from Dai Mubai. The way he looks at you is off.” “Musheng, did you overdraw your soul power? Come lean on me and rest.” “Musheng, they say you're a soul beast?” Tang San's fingertips brushed over his delicate features, his tone firm. “So what? You're mine.” Bai Musheng looked at the person in his arms, whose possessiveness was practically palpable, and muttered to himself: Wasn't the male lead supposed to be aloof? How did he turn into a fatherly boyfriend who keeps me wrapped in his arms? It wasn't until the tournament for the whole continent, when Spirit Hall questioned his identity and Tang San unhesitatingly summoned his Clear Sky Hammer, glaring at the enemies filling the arena as he barked, “Who dares touch him?” that Bai Musheng finally understood: This Blue Silver Grass, whose possessiveness knew no bounds, had long since twined its roots into his very bones and blood. “Look, Tang San, basking in the sun really does make you stronger.” He smiled, eyes curved like a lotus blooming toward the sun. “Mm.” Tang San tightened his embrace, his voice low as an oath. “But you're the only light I have ever had.”
