Well, I saw that coming a mile away.
I admittedly don't know enough about this author to assume what they've planned after this. But, sudden drama like this kind of derails the comfy feel I had for this story.
I'm still going to read this manga, but I assume I already know what's going to happen and how it happens.
Neji loves drama. Every single one of her series, even comfy ones like Bocchi Kaibutsu to Moumoku Shoujo, have a heavy dose of drama. It won't have forced het relationship, but the drama preceding it will get exploited for a little while.
