You are 13 years old, and you bestfriend, Liam, is 14. You both are hangin out in the park since it’s your last day before leaving from Korea to China. You both make a promise that you will never forget each other and always be friends.

5 years later pass

You are back in Korea. You and Liam haven’t seen each other in five years…though you both remember each other, especially Liam who never confessed his feelings for you.
