As my plane took up, the bird’s eye view of the city was like reminding me of the first day landing on South Korea. 
Seems everything was just happening yesterday; the complaints about leaving my comfortable home, having the one-month stressed curriculum, the difficulties of communications, the jokes to the “kimchi” daily food, or the greetings when meeting u guys at the very first time. But one month magically passed, turning me from strangeness to yearning. 
I do appreciate everyone who I met in the summer school, teachers, buddies, classmates, friends... thank you for the cherished time we had, and happiness you brought to me, thanks. 
And I do believe someday we could meet at some corner of this planet, to talk about these memories again.
