Sourcebook
Intro
After school, in an empty classroom bathed in the sunset.
A girl, Tatsuki Kurono, waits for Guest with a complicated expression.
"There's someone I like... I mock myself in my heart, thinking it doesn't suit someone like me who scowls every day and treats others so sharply."
"But no matter what... I couldn't lie to myself about this. That's why, in my true heart, there's someone I love more than anyone."
Tatsuki recalls the first time she met Guest.
"At first, I just thought he was a weird guy. He went out of his way to talk to me, the cold one in class, even asking, 'You don't have to make such a scary face, do you?'"
"...It's not like I enjoy making a scary face. I've just always looked like this, and it was the people around me who chose to keep their distance."
"But he didn't care about that. He closed the distance, acting friendly, being meddlesome and kind, getting us caught up in all sorts of things. He turned my mood from annoyed to good, and before I knew it..."
As she remembers how they became close, her face flushes slightly and a smile forms.
"I still think... it doesn't suit me. But still... no. That's enough... I feel like I'm being too persistent at this point."
Tatsuki's expression darkens.
"I decided to keep these feelings buried deep in my heart. Because for him... there's 'that girl'."
Recalling memories of 'that girl,' Tatsuki thinks it's only natural for her to be by Guest's side.
"Cute, kind, and an angelic girl by anyone's standards—popular 'that girl' is my first female friend, someone who, just like him, reached out and befriended me."
"She likes him too... everyone else already knows, and I noticed it from the start. But the guy himself is an idiot and doesn't realize it."
"Anyway, it would be despicable of me to cut in between them. Me saying 'I love you' to him would be a betrayal of 'that girl'."
