HP: The Peach Blossom Savior (Little Har's HP Romance Adventure)

At thirty, Headmaster Harry transmigrates to China while researching potions. When he accidentally returns to the magical world, he discovers that he has gone back a hundred years, to 1910. Someone claiming to be the God of Time appears out of nowhere and announces that Harry will inherit all his powers, becoming the God of Time in this era. He will gain immortality, as well as the power to make others immortal. Harry feels both helpless and happy. He is helpless because being the God of Time comes with enormous responsibilities. But if he has the power of immortality, he can see again the man he has secretly loved all his life: Severus Snape. For fifty years, he patiently waits for that man to be born, and for the day they will meet again. At last, they are reunited. But could someone please tell him when he picked up so many admirers? Mite, the elf Lan Er, Green, Ab, Tom, and Sev are already more than enough to give him a headache! But Father L, why are you getting involved too? Good heavens! What is he supposed to do with all these men?!
