Just gonna say your bebeing pretty unfair to wulin when Gu yue nearly died to a martial fusion technique he ddidnt he hesitate to protect her event he would die and not see his parents again. As for him stabbing her Gu yue planned that since she made him think she would kill everyone he cared about while he was letting her kill him which messed up his thinking ledding to him trying to protect his friends. Lastly when committing suicide he did it becauseblike he said Gu yue didnt have anyone who love her so he decided to be with him even it meant giving up everyone else he cared about and cared for him in his life. While with Xuanyu he wasnt as close with him as Nana and couldnt justify spending his time guarding him since he both had a job and didnt know he was his son. Theres a reason the minute he figured things out by breaking tge seal he have up everything in order to guard nana and protect xuanyu.

update pls
