Sehun was an ordinary boy. 

He was not really famous in his school. He was quiet, didn't really know how to socialize, and didn't have many friends. 

But, he had one friend, named Baekhyun.

Sehun really wanted to be an astronaut. He really loved the universe, the stars, the planets, the space, the galaxies, everything that's related to astronomy.

But, his father didn't approve it. He wanted Sehun to continue his company.

Sehun was so desperate. He gave up about his dream, decided not to go for it anymore.

But, in the middle of his disappointment, a boy, came from nowhere, appeared.

It was so strange, but Sehun loved it.
