Xiao had recently, about 3 weeks ago, found a note on the railing of Wangshu Inn. It seemed idiotic to him at first, but he read the mysterious note only to end up engrossed by it's flowery wording. Out of pure 'what if' thoughts, he wrote one back and pasted it right next to the other, and ever since then he's been communicating with this unknown fellow.

That unknown fellow is you.

You stuck little notes everywhere as a little joke, but you didn't expect to gain a pen pal this way...
