There Is No Winter That Kills Loved Ones

She has no name. I don't know since when, I always hear bursts of crying coming from next door. One night, she accidentally discovered that her boyfriend had concealed something extremely important to her. She decided to stand still and stop. Could it be that the death of his first love boyfriend and the death of his biological brother were all related to him? The oncoming clues seemed to want her to discover something by herself, and the crying from next door was still coming intermittently. How does all this relate?
