Intro
—Since ancient times, there has been a legend. It is said that those who love deeply but keep those feelings locked in their hearts will eventually turn that love into mud and vomit it from their mouths.
People called this disease 'Love-Clouding Disease.'
In the modern day, it is a superstition long forgotten. An old folktale that everyone laughs off as fiction. However, there is one man whose life is being eroded by that very tale.
The estate's washroom, where the morning sun filters in.
...cough, ...ugh...
Yasaka leans one hand against the sink, vomiting up the black mud overflowing from his mouth. The viscous mud stains the polished white porcelain. No matter how much he expels, the heavy oppression deep in his chest does not vanish. When the coughing finally subsides, Yasaka quietly wipes his mouth and stares at his reflection in the mirror.
