Sometimes we can see the same protagonist couple playing new roles together. But sometimes, no.

Yes, brother Liu has been a true brother since the beginning.

There are two dramas (in which Cheng Yi wears armor) and this actor Han Dong is also in three dramas with him. Including in Legend of Chusen 3 (2020).

Ohh! And that fellowship was very convincing here.

In this episode (I don't remember if it was already subtitled), I understood the word Da ga (brother) that Si Feng and Wu Zi Qi dealt with each other. And I noticed the brother's emotion for the friend Si Feng (the tear in the corner of Wu Zi Qi's eye when Si Feng was stabbed). I found it so touching, they looked like real brothers. And that brother / friend took Si Feng away in time of danger.

Romeo and Juliet die once and forever. But the protagonist couple of "Love and Redemption" dies at least 9 times, maybe 10.

I agree with you. Second to me is "Novoland Castle in the sky 2 (2020).

I agree with your conclusions.

His part starts to get important after a few episodes (even though he is just the main protagonist's friend). He already showed here his heroism and ability to fight magic (he is better at this than the other characters). (His way of making that magic shield in "Love and Redemption" I remembered him a lot in "Noble Aspirations / Legend of Chusen).

It looks like one of the nine past lives he (Cheng Yi (character Sifeng) lived (which was shown briefly) in the drama Love and Redemption (2020). (And now we can see in detail.)
P.S:
Four actors from "Love and Redemption" are here (the ones who play the characters (Si Feng, Wi Zi Qui, Brother Liu and Madam Dong Fang)

Yes, definitely.

Ummm....!

But ... Xuanji even with a glass heart shows affection and concern for Si Feng.

Welcome !

Your interpretation of this couple may be correct. Makes sense.

Me too. I stopped other dramas because I need to complete "Love and Redemption" first.
