Novel game in which you are talked down by your sick brother-in-law.
He loves you, but he has a problem that he loops you around when you give him an unfavorable response.
But, well, that's because you say strange things to him. Sis should like me, don't you agree?

It's dark from start to finish, and there is no relief, but there is love. In his own way.
