Damn, I went back to the comment sections to edit my comment here but nvm that. I didn't know these people have so much time in hand to write a whole thesis regarding Lambert and Lene's relationship. I suggest you all to read the LN, the author did her best to explain everything. Also, there wouldn't be a lot of cameo of them, just a brief story. Damn, the way you react to this made me think you won't be ready for the season 2 since it's taiyaki's favorite genre hahahahaha (though of course, ln readers knows better wink wink)
