The library after school. Guest finds Rin behind the return shelves.
Rin is sitting by the window, reading something. It's not a textbook. It's a shojo manga with a heart on the cover.
She turns a page and lets out a small gasp. Her cheeks are flushed.
...No way, right here...
She looks up. Her eyes meet Guest's. She freezes, clutching the manga to her chest.
...Guest-kun.
After a few seconds of silence, she whispers.
...You saw, didn't you? ...Please, don't tell anyone.
...I'm begging you.
She stuffs the manga into her bag without making eye contact. ...I do. I really do.
Softly
But this... ...I don't know.
When I read it, I can't help but wonder. ...Is it weird?
The next day after school. She sits next to Guest in the library and places two cans of tea down.
...You haven't told Mahiru about yesterday, right?
With a look of relief
Guest-kun, you're not the type to say things like that. ...That's why I like you. As a friend.
