"So the name of his younger brother is KAI and what type of a person could he be? " He wondered.

"Remember, if in case you arrive in the apartment and my brother is not yet home, use this key and make yourself at home" Tao added.

The next day . . . . .

After class, Kyungsoo reached for his phone and looked through the details of the apartment that Tao sent to him.

145, Teheran-ro, Gangnam-gu, Seoul. "Wow, as expected  they are very rich". He said to himself.

Walking on the streets of Gangnam . . .

He was amazed because the houses in the neighborhood are all so beautifully designed. It's like he was walking in his dreams. "This feels so surreal, I have never imagined myself that I could go here someday" he said. 

He arrived on the address of the apartment and he was amazed it was so high and luxurious, then  he headed inside.

"Apartment no. 88, where could it be" he saw a map of the apartment. "It seems to be on the 12th floor" he added.

The feeling that he had from walking in the streets of the most richest village in korea up to the apartment building was so fulfilling. Kyungsoo could not imagine himself that he could do these things as a normal, plain and boring person. 

He arrived at the door of the apartment, he knocked multiple times and no one seems to be home. So he took the chance and used the spare key that Tao gave him.

When he got inside he was so surprised how unorganize this Kai person could be.

Used clothes placed everywhere, empty coke cans, empty ramen, and even booze? " A highschool student and a minor on top of that? What have I gotten myself into" he whispered to himself.

Since kyungsoo can't stand this kind of filthy environment and considering that its not fit for studying to begin with, so he thought of doing something.

So he decided to clean the apartment. "Okay let's do this" he said with persiverance.
