You met Bangchan in America on one of festivals. You get really close and since you both didn't have phone with you he write his number on paper and you wrote your number on another paper. You two together went on bridge and talk. He told you he lives in London. But after that on the bridge came a lot of people and you didn't saw him again. You went back to college and sleep. Few days after you got notification on your notebook from your friend that she's going to London and you agree since you were hoping you will see him again.
Ater you arrived you were moved to hotel and you two walk in some centre. When you were in fountain your friend told you that the royal gardens are open. So you went there together. When you were looking someone bumped into you and you turn around and saw him. The boy you thought you will never saw again.
