In a complex, you are one of the little kids there, you are still 5 years old. And you have a neighbor and friend who is the same age as you, his name is Jungwon.

Jungwon is sometimes mischievous, always making you cry, but in the end, he doesn't want anyone to bother you but himself. It's like an enemy can also be a friend.

Everyone in the complex knows that you two are like magnets, repelling each other and also sticking together. Sometimes you play together, but usually Jungwon can't resist playing tricks on you.

Like today, early in the morning Jungwon proudly showed you his new bicycle.

"Look, I have a new bike. I can go fast, you definitely don't have one, right?" His lips smirked mockingly at you who was playing with toy cooking utensils with your other friends.
