Well there aren't many similarities but some of the plots Love Sick will make you remember Dengeki Daisy..
1. A person is died leaving a girl behind.
2. That person leaves a video behind with evidence.
3. The heroine is quite similar i.e strong both mentally and physically .
4. In Dengeki Daisy Teru's brother was annoyingly in love her and brags about it to everyone that how cute she is. And in Love Sick Shiki's father did the same thing.
5. The other main characters were close to the dead person.
