Nani Ga Anata Wo Sousaseta
いしだあゆみ Lyrics

The song 何があなたをそうさせた by いしだあゆみ talks about two hearts that were believed to be tied together but were forcefully untied and left behind. The singer questions what made the other person do this to her and what was wrong with her that led to this. She asks for an answer and decides to wait until sunrise to make a decision. Meanwhile, she is looking at a cold coffee and waiting for a resolution. The other person avoids her and speaks to her formally, making the singer uncomfortable. She is scared to go back to the room that they once shared and contemplates death as a way out of her misery. However, she remains alone even when the door is opened or the lights are turned on.

The lyrics suggest a relationship that ended unexpectedly and was painful for the singer. She is confused about why it happened and blames herself for it. The other person seems to have moved on and is avoiding her, making her feel lonely and abandoned. The singer contemplates suicide but remains alone, unable to move on from the pain.
