That's exactly the point. In truth he's a ticking time bomb. All it would take is one little misunderstanding -him seeing Hatsuki with another man and thinking he's flirting, or him getting home late one night and the seme thinking he's cheating on him and he'll probably fly into a rage again. Hatsukoi will probably be in and out of the ER regularly for the rest of his life -which probably won't last long because he'll probably kill him during one of his rage sessions probably within a few years of them living together. This is what happens to real life abuse victims, and I hate that this story glamorizes it.
Well said.
OMG at one point I couldn't stop the tears from running!!
The seme is a real sociopath, and even though I'm happy that he finally recognized poor Hatsuki for someone totally lovable, I can't help being scared that he'll go berserk again - he's so unstable!! What will happen when he talks to his brother again? Poor Hatsuki, I felt so sorry for him, he looked so unhappy, how he endured all that abuse I don't know! :[
