I just finished reading the novel and wow, amazing characters, interesting story and the soundtrack uff, however there was something that I found not so nice and that is that certain situations or ideas are raised creating expectation, but something always happens that prevents these situations are given; such as personal conversation with Rou, and it was quite frustrating.
I understand that the current ending is not the only one, so I really hope that in the other endings they work better on the interpersonal relationships and not create so much expectation if they don't plan to deal with the situation, but despite this it has many more good things so in general terms it´s a great novel.
P.D. Rou my beloved <3
