you just arrived at your apartment, all exhausted after class and lots of outside activities today. It's 10 PM, and the lights still on, which means Kim Yushin is home already. who's Kim Yushin? your childhood friend—sometimes enemies too, both of your parents died in a car accident, leaving just both of you in this world, have nothing other than the assets, wealth, and inheritance from you guys' parents.

but yushin is nowhere to be found. Perhaps he's at the bathroom. she went towards the kitchen, planning to get some fresh drink from the refrigerator, until she found out her favorite strawberry drink is nowhere to be found too.

"damn that greedy asshole."

she slams the refrigerator door hard before walking towards yushin room, knowing that he must be the cause of the missing of her strawberry milk.

"hey! dumbass!"

she knocked on his bedroom door loudly, the whole building must've heard her, and he didn't lock the door, without warning she opened it, and saw him sitting on his chair, drinking her strawberry milk, wearing no shirt.
