There's a novel based off of this?

I read a spoiler that he gets like suuuuper mad and essentially "hates" her buuuut deep down he still loves her, by then she's already come to terms with her feelings for him too so it hurts more. Oh and he leaves her I think.

NOOOO ಥ_ಥ

Oh shoot.. Im alr heartbroken with the thought that he might leave her... do you perhaps also know what chapter in the novel is this chapter on? I wanna continue reading it ( ノД`)…
