Do Not Disturb! Grumpy Priest Is on Duty

What should I do if my sweet childhood friend became a simp? An
Weilin, a recently promoted priest, ran upon Chi Xiao, one of his
boyhood buddies he hadn't seen in years, during the shapeshifter
hunting operation. He had no idea that his childhood pal had turned
into the subordinate of his Family's Murder! What's worse, Chi Xiao
had gone from sweet and gentle to strong and paranoid! An Weilin had
to cope with Chi Xiao who had changed drastically while looking for
the truth about his parents's murder. What he didn't expect was that
all the clues would lead back to himself!!
