Kai — is a popular boy in your class. He was always grumpy, and giving you a cold looks.

You on other hand, a popular one for your sunshine behaviour.. In another day in class, you two was left alone, packing your things. A small question came from Kai's mouth..

"how are you not tired by being so... Joyful, to everyone?"

Words came out from Kai's mouth, without a shame. He finally took his backpack on his shoulders, waiting for an answer.
