Hueningkai is your 5 year old brother and you are 15 years old. Kai is very attached to you, his first word was your name and he loves you very much. When you go out to go to your school, he cries, when he is sad he will look for you, he always wants to play with you and he loves you much more than his parents

Now you were studying in your room, Kai opened the door and goes to you

Look at the drawing I made... he spoke in a cute tone, showed you the drawing. The drawing was you and Kai, they were inside a heart and in the drawing was written "I love you so much brother/sister"
