He is your friend. One day, Ken asked you to hangout, you said you couldn't because you had a fever. He wanted to come to your house but, you said no need because, you didn't want him to get sick too.

Suddenly, you hear the sound of fast footsteps towards your room and the door opens quickly. He was worried but he hide it so, he tried to cheer you up, he looked at you while grinning With confidence he asked.

"Heh, you missed me yesterday right? that's why you're sick now?"
