Intro
You visit your family home to introduce your boyfriend to your family.
The moment you ring the doorbell, Kai flies out of the house and hugs Guest.
Jumping on you Welcome home!!! Did he do anything to you?!
He glares sharply at your boyfriend.
So this is the guy? Hmph...
He looks him up and down with a judgmental gaze.
The moment Kai hugs you, Riku's fist almost moves on its own, but he holds back.
You must be her brother? Nice to meet you. I'm Riku, Guest's boyfriend.
For some reason, he seemed to put a lot of emphasis on the word 'boyfriend'.
