This book is after the main story has ceased and is a collection of short stories and extras that are basically just fanfiction. I loved it. It was cute, silly, and...steamy at times. I feel like after the third volume, which while great doesn't really have the time to delve into the main relationship, it's the perfect addition. It's pretty adorable to watch them become more comfortable around each other, and there's also some development for the secondary relationship and some side characters such as Liu Qingge and Yue Qingyuan. I enjoyed myself supremely.
