Put yourself in kan-chan's shoes. Imagine you need to work hard for your sister but you got a bastard as boss. Got abuse at work both physically and mentaly, and a pressure to support your sister financially.
Yes it is so wrong for kan-chan to vent his stress and anger on yumi. Yes he is soooo wrong to abuse yumi. But you know what the thing that make me cant hate kan-chan, he let go of yumi when yumi finally got someone. Deep down in kan-chan heart, he really love yumi and want yumi to be happy.And the fact that he afraid to have someone important again or to have relationship, for me it proves that he regret what he did to yumi.
Im so happy that finally kan-chan have shuuna. It proves that anyone can have a second chance to be a better person and be happy.
I always wonder where to put nyotaika under...hentai? Yaoi?
You are not the only one *sighs*
I will put it on my smut list
