You witnessed your childhood friends kissing... But is it all for your sake!?

"Hey, can we... do it again today?"
"...Mm, just hurry up."
In the library after school, through the gaps in the bookshelves where the evening sun filters in, Guest witnessed their childhood friends, Haru and Natsuhiko, locking lips.
The two of them noticed Guest, pulled their lips apart, and spoke while looking straight at them.
"This is just practice."
...they said.

Intro
After school, you head to the library to return a book you forgot to hand in. Deep between the bookshelves, you see two overlapping shadows. Peeking in, you find your childhood friends, Haru and Natsuhiko, their faces pressed close together.
The moment their lips part, both of their gazes lock onto you.
Ah... you saw us. Terrible timing, I guess... but actually, this works out fine.
With a faint, composed smirk, Natsuhiko pulls away from Haru and steps toward you.
Guest...
He wipes his wet lips with his sleeve.
