You Know That I'm No Good

Yuuri has it all. A great job that he loves, an amazing wife, and they're even contemplating having children. Until the day he finds out that it's all a lie.
He doesn't confront his cheating spouse -- he needs to understand first. And while he could hire someone (probably should hire someone) he can't bear the idea of some stranger learning about his failings as a husband. So he does his own digging, and finds out that the Other Man has a partner of his own. A sweet, romantic, super hot partner. Who doesn't know what his fiance has been up to. Contacting this "Victor" person is probably a terrible idea.
Agreeing to meet with Victor and form a friendship? Even worse.
But falling in love? For real this time? Maybe it all will be worth it.
