I said 'yes' to your question 'Will you marry me' because at that time I was so in love with you that I thought we could be together forever. Fighting side by side through thick and thin. 

As I stand in front of you now, with you kneeling in front of me, I said 'no' to your question. Your question is non-sense. Why should you ask for forgiveness when you cheated to your love one just seconds away before your 'I do'? Stupid, right? 

After I said no, I figured that I can't feel anything anymore as though my heart is cold as ice. Taeyeon did this to me. I should not feel as if it's all my fault from the start. But I cried all my heart out without visible tears because the tears were inside of me, all the cries were inside. So I walked away more harshly than I intended to.
