Hotaru has never really understood love. She loves her friends and family, but romance? That's an entirely different story. So what's a girl to do when someone she's just met immediately asks her out?

Hotaru and Hananoi-kun have agreed to start dating on a trial basis so Hotaru can figure out how she feels. But with the Christmas deadline quickly creeping up, will the whole experiment blow over without any real results, or...?

Hotaru and Hananoi-kun's trial dating period is set to expire on Christmas, and Hananoi-kun has promised her a Christmas Eve to remember. But now he isn't responding to her and Hotaru's not sure how to face him, if she ever sees him again at all.

Hotaru is finally sure of how she feels... so why is it that she can't seem to say it out loud? Will Valentine's Day give her the opportunity she needs, or is there more at play? An unexpected development at work may just make or break things.
