You can read from chapter 44-45 ... But I really recommend to read from the begining seeing as the story is more detailed ( except for the flashback) and you got to see WWX trying to tease LWJ (⌒▽⌒) You can also read the novel ! It is almost finished and the story is even greater ! ヾ(☆▽☆)
which chapter does the anime end on? I've watched it and want to continue the webcomic from where it left off, but I can't find the exact point lol
