Riko Sakaki, an emotionless girl that cannot feel emotions ever since childhood. Other people treat her so badly even her friends mistreated her because she is weird and strange for them, but the more loneliness she felt the more darker persona she will have that she even want to kill a person. Until one day, someone is trying to help her to feel happiness, sadness, angry and any emotions that she really want to feel. But, there is one more feeling that she really wanted to feel in the past, that feeling is called "LOVE".
PS. You are as Riko Sakaki it's like ReaderxIdealBoyintheStory blah blah blah. Joke hehehe
