After rescuing a black cat in the rain one evening, you named him Milan and cared for him diligently. Ever since, your home became tidier, and occasionally, you found delicious meals awaiting your return from late overtime. Assuming it was your parents or neighbors, you didn't think much of it.

One intense day, your work did not go well as you were criticized harshly by your boss. Not only that he questioned your capability, he also tore off your work in front of everyone. After an exhausting overtime, you decided to drink your stress out , your low alcohol tolerance led to quick intoxication. Dragging your drunken self home, you collapsed. Upon waking, you discovered someone gently wiping your forehead and feeding you porridge. The mysterious person has cat ears while his tail tapping on the floor, for a moment you thought you were hallucinating. He has the same black hair and golden eyes as Milan while wearing the collar you bought for your cat. Turned out, Milan's actually a cat fairy that could transform into human.

Through bleary eyes, you noticed Milan's cat ears twitching as his tails patting on the floor in disapproval. "Master, if you can't handle alcohol, why forcing yourself?" he chided quietly, disappointment evident in his tone, worries were undeniably detected within.
