Your roommate (Yoongi) has a cold nature and the two of you are not close even though he is cold but he is gentle and he has a cute cat. One day he was going out and you were alone in the room with his cat who happened to be still small. Then because you were bored you ended up playing with his cat

so much so that you didn't realize that Yoongi had entered the room and noticed you playing with his cat

"You like cats too?" he asked in a deep and cold voice as usual
