Deyunshe: the Happy Life of a Tiger Cub

The heroine, Little Cutie, is the only junior sister of Haizi generation. She is also the good daughter of our Tao'er and the chairman (who is not her biological child), and the darling of the men in Deyun Club. The heroine has an unstable personality. She is the reincarnation of a white tiger, so she can become a tiger cub or a cat. The heroine's baby will have estrus just like cats, so what will happen during this period?
