Wait. People are really surprised by this development?. It was set up from the literal first chapter. Or were they just looking at pretty pictures. That cant be it either since they also do a good job of conveying general emotional context. What the fudge people!
I can kind of understand why some people would be surprised cuz this manga has been running for like 3 years and releases monthly and I forget a lot of stuff here and there. This is why I've read this manga for like 7 times already just to keep up with some stuff.
