Both are very dark dramas that talk about more sensitive subjects~
Although the plots are pretty different they are both sad love stories that the characters had to go through a lot to be with the person they love. They are both very dramatic and once you start you cant stop watching, wanting to always see what happens next.

Similar ML that are cold and mean to the girl that likes them but later warms up to them and does cute things with them. A little bit different because it is a high school love story and the girl already originally liked him from the start but still a very cute love story like Touch your Heart.
