Quick Transmigration: My Daddy-Type Boyfriend Spoils Me Rotten

[Two male leads, both powerful, both devoted, 1v1, top, no split personalities] When Ming Jiu, the young prince of the Underworld, was about to inherit the throne, a trial of the heart stopped him in his tracks. To understand and overcome it, he had no choice but to seal away his memories and power and travel to three thousand lesser worlds. Du Shuo, the spirit of the Peach Blossom Divine Tree, had watched the young prince grow up and couldn’t bear to let him go alone. He secretly followed, intending to protect him from the shadows, but never expected... The refined and noble Imperial Preceptor falls for him at first sight and willingly steps into the whirlpool of power, all to protect the young emperor he holds dear. A newly awakened vampire corners the blood hunter guild leader he abducted. “I want to kiss you!” “Can I?” At their first meeting, a warlord in the Republican era grabs his bride, whom he married to bring himself good fortune. “Let me hear you call me husband!” In an ABO world, a gentle, sunny junior wraps his arms around his moon and coaxes him softly. “Senior, hold me~” P.S. The main characters knew each other long ago, and their feelings are mutual, but one doesn’t know it and the other doesn’t dare say it. They fall in love at first sight in every world, and their relationship develops quickly. The bottom has a somewhat prickly personality and tends to overthink, but at heart this is all sweetness. The author is a beginner still finding their feet. Comments are welcome; I’m happy to take suggestions (except from nitpickers).
