Maybe it's just me, but I didn't find it disturbing, to me it was actually sad, and it's not like Yui actually loved Kei, people say you get attached to the person who messes you up to the point you think you love them. (。•︿•。)
I agree there are other works more disturbing than this.
Even if it's really disturbing it's only natural cuz it's a “psychological” manga, lol what do they expect? flowers and rainbows?
