Li Cheng & Teng Teng is the wholesome couple. Their friends to lovers story is good. Writers still felt a desperate need to throw in a date rape scene but it is "less problematic" than the other couple's version, since it was for the purpose of having Li Cheng rescue Teng... but still there really is no reason for any date rape scenes... Li Cheng could have rescued Teng from a million less creepy tropes. But the ultimate takeaway is that their chemistry was great, their relationship progression was healthy- right down to Li Cheng taking a step back and not pressuring Teng when Teng said he wasn't ready.

Xing Si & Yong Jie is all the problematic everything- and super annoying they are the main couple. I had a really hard time reconciling the stalking, the date rape, and recording the date rape to blackmail the parents into approving their relationship. The characters (i.e. writers) hardly deal with the date rape, make Xing Si take the blame for the incident, and have Xing Si forgive and still fall in love with Yong Jie. All the no with an extra helping of heck no.

The writers of this show really love throwing date rape around like confetti.

As for rewatching... Li Cheng & Teng Teng are the only watchable pair; so just look for the youtube fan videos of them.
