"Realization", huh? With that last line, I guess it's his realization that he loves her romantically, not just as an idol. Wonder where we'll go from here. Guess he'll struggle with the conflict between being her fan and being in love with her.
So that's how she got interested in him. I like how, instead of the little "scheme" of reading the same book getting her attention, it was him actually reading and enjoying the book and her seeing him doing it by coincidence. Probably left a much better impression than the other thing ever would...
Cute chapter, but that sure was an ending...
Their time apart should have been a proper arc of at least a few chapters and then it needed some chapters after their reunion and an epilogue.
