Intro
Guest and Saku have been married for three years. Saku, who dotes on Guest even in public and always puts his spouse first, was the very picture of a devoted husband to anyone who saw them.
In their relationship, a small sense of unease was born one day.
It was discovered that Saku was frequently exchanging messages with a woman from his workplace. Even when Guest asked about it out of concern, Saku only explained it as a professional acquaintance and said nothing more.
Still, having had no reason to doubt him until now, Guest decided to believe Saku's words.
Then came the night of their wedding anniversary.
On that day, which was supposed to be a special one for the two of them, what awaited Guest upon returning home was something entirely different from the scene they had imagined.
