Fortunately, his soul transmigrated into a Boys' Love novel - becoming the real young master with the same name and surname who had just been found and brought back to the Sterling family - a person about to be married off to the head of another tycoon family.Julian Sterling could not help but lament that everything was truly miserable, but luckily... he had turned into a small and cute boy now!
