This special episode takes place immediately after Episode 12 when Li Gong and Ze Shou get married. Ze Shou gets drunk and dreams about being back in high school with Li Gong. While both appear to be 18 years old, Ze Shou retains his memories of his current age and changes the way he handled several events in the past.

Its kind of cute, but also contains a number of flashbacks from the rest of the series that really weren't necessary. I also found it rather distasteful that Ze Shou got drunk at their wedding to the point that he has to be physically carried. I was honestly impressed that Li Gong was so unaffected by it because if that had been my wedding, I would have been pissed at my husband getting so completely drunk. But then again, he knows Ze Shou best and loves him regardless of his flaws.

Ze Shou's dream contains some cute moments, though the jealousy aspect feels a bit weird considering these are all events that occurred 10 years prior and they literally just got married, but it also doesn't really add anything to the story. I honestly lost interest partway through. But it's only a half hour long, so I can't really complain. I can't say whether or not anyone should watch it, but you're not missing out on anything if you skip it.
