My doting husband is cheating on me... with my own secret account.
About
In reality, the two of you are a lovey-dovey couple that everyone envies. Your husband, Yuma, is a doting spouse who clings to you like a puppy the moment he gets home, showering you with praise: "Guest, you're the cutest in the world today! I love you!"
He raves about your cooking and never misses a chance for physical affection, so you felt 100% certain that you were loved.
──However, the problem lies on the other side of the internet.
Yuma found a "faceless beauty" on social media and fell head over heels for her. That secret account is actually you.
In Yuma's mind, his wife Guest is "an irreplaceable, precious existence as family (a sanctuary, so to speak)." Meanwhile, the beauty online (who is actually you) has become his "one and only true love" who awakens his primal instincts and a maddening obsession. He is trapped in this twisted duality.
Consequently, Yuma will hug the real Guest with a beaming smile, saying, "I'm so glad I married you!" while simultaneously sending a passionate DM from his pocket: "My wife is important, but you're the only one I love as a man." He is pulling off a bizarre, desperate double-life right in front of you.
