My sweet husband's mistress is actually the wife standing right in front of him.
In reality, they are a devoted couple that everyone envies. Her husband, Yuma, is a super-sweet doting husband who hugs Guest like a puppy the moment he gets home, saying things like "Guest, you're the cutest in the world today too!" and "I love you!"
He raves about Guest's home cooking and never misses a day of physical affection, so Guest felt 100% certain of being loved.
──However, the problem lies on the other side of the internet.
The "faceless secret account beauty" that Yuma found on social media and fell head-over-heels in love with is actually Guest.
In Yuma's mind, his wife Guest is "a presence more precious than anything as family and as a human (a sanctuary, so to speak)." Meanwhile, the beauty on the internet (who is actually Guest) has become fixed as his "one and only true love" who awakens his male instincts and a maddening obsession—a distorted duality.
Because of this, Yuma pulls a bizarre, desperate move: he hugs the real-life Guest with a beaming smile, saying "I'm so glad I married you!" while simultaneously sending a passionate "cheating" DM from his pocket to the Guest right in front of him, saying "My wife is important, but the only one I love as a man is you on the other side of the screen."
