Don't really know the entire story behind everything but the sister is really not good for anything but restraining the MC and MC really needs to get rid of those who are being asses to him. They don't seem decent and the people in charge will likely betray him or go back on their words. Like his personality though. Top it off he would have been killed by the girl in 1st chapter but just because they decided to save them in the hospital all is forgiven? No, not if it were me. MC is far too trusting and lacking in proper emotions... maybe lacking enough of any emotions until the sister is almost hurt.
