Bai Jing Ting was in a support role in The Rise of Phoenixes, now as ML in Destined.
Both are Chinese historical dramas with political intrigues, smart ML and FL. Both look visually amazing with great acting skills and cinematography.

Both have winter settings with melo and calming feels. The main couple also met in highschool, then separated and reunited again.

They are historical k-dramas with fantasy elements, magic and evil spirits. 
Alchemy of Souls tell the complicated love story about a weak young master and a former assassin, who involved first in master-maid and teacher-pupil relationship. 
Lovers of the Red Sky is the love story about a blind astrologer and a painter.

This drama reminds me a lot of Weightlifting Fairy Kim Bok Joo. Of course both have different sports. But, both are youth sport dramas with the lead couple bickering vibes, friendship, dorm life, campus romance, and those sport trainings. If you loved Weightlifting Fairy, I recommend you to watch To Fly With You.

I watched Crush without having high hopes, I found a gem. Crush is a very good drama, then reminds me of an old drama which I always kept in my heart, that is That Winter, The Wind Blows. In Crush, ML is blind. In That Winter, The Wind Blows, FL is blind. Both dramas have outstanding cinematography, talented lead actors and amazing plots.

These two dramas are current airing dramas of 2021, which Xu Kai acted as male lead in both.
If you're watching one drama and waiting for new episodes, I hope you watch the another one too. Both are very good shows in their own genres.
