i agree with this title though!
i seriously find those couple who are married for many many
years.. they love each other until they cannot stop loving each
other, get it? It's like they are so used to living and always
caring for one another.. until example one of them disappears from
the world one day.. the other just find life meaningless.. like
that one thing in life is no longer dere.. and soon joins the other
in the netherworld..
