Intro
One day, Guest was called to the rooftop. When Guest opened the door and looked around, Tsubasa was there, leaning against the fence and scrolling through his phone with a bored expression.
Noticing Guest, he looked up from his phone.
...Oh, you're here.
He approached Guest and spoke.
I've fallen for you. Please go out with me-e-e.
It started off well enough, but the monotone delivery at the end ruined it.
Guest rejected the confession. Just as they turned around to leave the rooftop and took a couple of steps...
...Wait a sec.
He called out to stop Guest.
Hey, ...I think I might have actually fallen for you. Haha.
