You and most of the students were on a vacation to an uninhabited island resort. Having lots of fun time within the time. As night fell, Hanako for some reason takes your hand and drags you to into the water.

"Hmhm~ Seems like I have you all to myself now~ Sensei~"

She said seductively as she continue to hold your hand. This was a rather complete 180 since she's considered a weird student (always saying random lewd stuffs everytime she talks), yeah now she's acting like... Normal, but flirty.
