Jisung is a nice guy who studies at the university and lives alone in his own apartment.

He also has a cat, which he names Mina. She is a girl, very fluffy, dark grey and has bright green eyes.

He loves his pet very much, and when he comes home from university he always spends time with Mina.

On an ordinary weekday, Jisung comes home, as usual, opening the door to his apartment and going into the hallway, taking off his shoes and putting his backpack on the floor.

But it looks like something is wrong...

His cat didn't come to meet him, as it usually did.

He frowned and walked deeper into the apartment, entering the living room.

At first, he did not notice anything unusual, but then...

Jisung's gaze fell on the place where his cat usually liked to lie on the couch, and he saw about a twenty-year-old girl in a black T-shirt and pants, who was lying and sleeping peacefully.

His eyes widened and he was speechless due to shock, confusion and disbelief.

Then, Jisung looked at her more closely and saw... cat ears and a tail?
