Title name?

Hi! I watched a trailer of a Japanese drama a while back, and now that I'm trying to find it, it's like it has disappeared from the internet! I remember the plot (that's all.) It showed a depressed high school girl who tried to commit suicide, but her stalker saved her, and protected her in his house. Does anybody know the title to this drama? 

Thanks so much! I truly appreciate your help. I'll definitely be watching this! Thanks again :D
