"This is our last day together Yunho seonsangnim" I said. "Why are you still calling me 'Seonsangnim'? We're not in the school anymore Yuri-ssi" Yunho answered. "You can call me 'Oppa" he continues. "Well.. Oppa.. Thank you for everything. Goodbye and Goodluck!!" then I smiled. "This isn't a goodbye Yuri-ssi. This is just the beginning" then he kissed me on my left cheek. I froze, I can't move and I don't know what to say, I just looked at him and he smiled at me. And then I heard his name, the airplane will take off in 10 minutes..
