I would say yes. It shows how Xue Jiao and Zhi Hua's relationship continues to grow, even though they still have a few hurdles to overcome. Shi Yun and Lin Jia Dong also get a character boost (even if you might not think so at first...). But I don't want to give too much away.

So if you want to avoid chinese censorship regarding time travel, I would really recommend stopping at episode 23, 32:50.

I would suggest watching the last episode up to 32:50.
