What I forgot is that I love you! I'm sorry, because I have been sad for so long, I have forgotten what it means, I love you! Love has no roots, but it has a traceable history. It's just, I really don't know. Love has been destined to pass me by since I was born. It's like, you never know how long this rain will last? Can you see a rainbow after the rain? Or, how beautiful can a rainbow be? However, even though the beauty you brought to me was so short-lived, I still thank you so much! Thank you for bringing me happiness. It's just, I'm sorry, I really don't know, I love you!
