Since 1845 (taeqi ver.)

what if I told you you can go back in time? well there's this one girl that she wished she can go back in time in captain kim's era why? she has a project in history, that she has to write what happened to captain KIM? how did he die? and who killed him. google couldn't answer that that's why she wished she can go back in time, but she didn't expect what would happen next......
