My parents died since I was 3, and since then an arranged marriage with her was decided. My grandfather told me that this year, Sooyoung and I must get married. But how? She's even younger than her little sister. 

"I'm always me. Well, since the day we became friends.." . Choi Siwon, what are you saying.

"Really? I never became myself even for once. Except during those memories we had."

"Sooyoung, I didn't say I'm not happy marrying you."
