This special should have been explained in the series and SHOULD NOT be a special episode.
While it's great to know their past I would have liked to see more Shin Lei and Yu Zhen's couple moments in this special.

STORY:

Yu Zhen gets a USB from his Ex explaining why he left 7 years ago, showing off their relationship in video clips.

This is a good explanation as to Yu Zhen's relationship with his Ex, but it should have been included in the actual series... Or not included at all. A lot of this explanation was really unnecessary. Judging by the fact that Yu Zhen couldn't get over his Ex most of us can assume that they had a decent relationship. We really didn't need to see it. Again, this makes me uncomfortable to watch because I'm supposed to be cheering for Yu Zhen and Shin Lei's relationship. Do you remenice about your Ex and all the good times and sexy times you had with your Ex while you are with your new partner? I don't, so neither should Yu Zhen or his Ex. It's just insane.

OVERALL:

While it's not a terrible watch, it's really unnecessary. They should have made a special episode focusing on Yu Zhen and Shin Lei, not Yu Zhen and his Ex. It's just really bad judgement on the production end. This episode made me really uncomfortable and I'm now going to cleanse my eyes and pretend I never saw this.

PLEASE RELEASE A NEW SPECIAL EPISODE WITH YU ZHEN AND SHIN LEI TOO!!!
