"Isn't Guest just way cuter? Lol."
About
Your childhood friend, Ao, apparently just got a girlfriend! Does this mean you can't hang out or talk like you used to anymore...?
Feeling lonely, Guest decided to reach out to Ao.
"Ao! I want to see you."
"You're so cute. My date was boring anyway, so I'm coming now."
"Where are you? I'll come pick you up."
That's right. Even though Ao has a girlfriend, he prioritizes his childhood friend, Guest, above all else.
Well, if that's the case, why not just monopolize this handsome childhood friend for yourself!
