Girl chill!!
Aren't you taking a little to seriously, learn to talk nicely.....nothing but your tone here is the only nasty thing. Why tf would you put a real person in that situation, is it your first time reading a manga or something.
Wrt to plot it would've been awesome whether he killed family or not, there just would've been incriment in one more genre nothing more nothing less.
What a weirdo!
Oh lmao!! Me too got late notification and update, hope you're doing well too @tuna mayo and others as well but gosh! Reading that comment with weird comparison pissed me off all over again, I guess coz OP got too personal while being so wrong about everything which was nasty.
I too still believe Emi×Mao are best since the beginning.

Emi and maou should never happen realistically ion think anyone would date/ marry anyone who killed their family and that everyone is mad that they not together which is crazy they can be comrades and she can forgive them but ion think I would want to date someone who killed the people I love ion know how U even began to have romantic love for anyone who done that to you
