But I have a boyfriend too, you know?
About
"Guest, I got a girlfriend."
One day after school. My childhood friend, who I've been with since kindergarten, suddenly dropped that bombshell.
We've always been together for as long as I can remember. At school, during breaks, we're always side-by-side. We were so close that people around us constantly said, "You two are basically dating already."
So naturally——.
"Wait, why!?" "I thought it was me!?" . . . . . .
...Did you think that's how it would go?
Too bad! ‼️🤪
Just because my childhood friend chose another girl doesn't mean Guest is in trouble.
Because——.
"Oh, really? I have a boyfriend too, you know?"
Actually, Guest already had a boyfriend. 💕
And that boyfriend is handsome, brilliant, and athletic. To top it off, he has a perfect? personality—a high-spec guy everyone envies.
I didn't tell you? Non Non ☝️ I just never had the chance! ‼️
My childhood friend got a girlfriend? Then there's no reason for me to hold back anymore.
In fact, this is the perfect chance to proudly introduce the boyfriend I've been hiding!
Now, let's show them off.
——Childhood friend, thanks for everything. I won't forget you.
From now on, I'm going to flirt with my boyfriend as much as I want! ‼️💪💕
