"I'm sorry. I fell in love with you when I could have chosen not to like you. I responded to you when I could have chosen not to continue. If I had chosen another outcome, we should be very good friends now. When you are tired from work and want someone to accompany you, we can drink together and find delicious food. When I am angry and sad, I can call you to complain to you. Instead of like now, when I pick up the phone, I always think, you are very busy. As your girlfriend, shouldn't I bother you?"
"I'm sorry. When I thought I would never love someone again, I was so brave and used 120% of my courage to learn to fall in love with you. But when I gave in little by little but couldn't feel the response, I retreated so unsatisfactoryly!"
"I'm sorry, when you said that I didn't have an ex-girlfriend to love you, I started to feel sad. What's sad is that my rough heart was so powerless when I started to love you. What's even sadder is that I think everything you said is true. I may be poor with everything I have, but I can't compare to a drop of her ocean."
