I dont know about the others but I actually like this.
Like the other comment, i think he did not abandon aka. he just left him in the wild because it is impossible for aka to act like a human.
And although this is quite common to say, harada sensei's works are the most fucked up ones that i have read.
I dont know if im petty or what but i really want Hamura to confront and be really mad at Jin for the kiss and him sleeping with Alex in the same bed. Like come on? You boyfriend is kissing someone in front of you and you did not bother clarify it and just kept it to yourself. If i were Hamura, i would even breakup with Jin right on the spot.
Im glad that when I first read this, it's already completed. Or else I would be cursing the seme to death when he inititated the break up when it's HIM who started everything. Anyway, here I am crying again because I got reminded by the Live Action's poster and came to reread this.
