The ending is perfect, in my opinion, and very much in line with Yan ZiJing's character, as well as Liu Yu Ning's interpretation of him. In a previous interview, LYN said that YZJ will not want to die in front of the people he loves, making them suffer emotionally as they watch him slowly die from the poison. So, like some pets do, he decided to leave home to die alone. While some may take this as an OE, I would say it's bittersweet. It is heavily implied that there's no cure for YZJ, and so he presumably dies not long after he leaves DW and co.

I am not sure how many scenes he will have, but it will probably be a lot lesser than his appearance in "Wonderland of Love". Especially if they are going to follow the animation closely, then the Sea God Domain/Island should be near the end, which will lead into Part 3 (if they even get to filming it). But if I am wrong and they try to cram the entire Sea God arc, then LYN should have more than just a cameo. But doubt it since he said his part this time is really small
