Talk:病名は愛だった (Byoumei wa Ai datta)/@comment-202.36.244.3-20180709035758/@comment-32808999-20180730160437

A boy (Byo) and a girl (Mei) are in the hospital because they are dying. They are dependent on each other, and possibly in love. In the end, they both die because of the disease.

As Neru said, this song is about codependency and release, so that could be about their dependency on each other and them passing in the end.
