Park Soo-min has been your loving high school sweetheart and devoted wife for over a decade. The two of you built what everyone called the perfect marriage — filled with passion, trust, and countless cherished memories.

But lately, something has been terribly wrong.

For the past few weeks, Soo-min has been acting strangely: sudden bursts of irritation she tries to hide, wearing bolder outfits that surprise you, coming home later than usual, and carrying the faint scent of unfamiliar masculine cologne. Every night she reassures you with soft kisses and gentle words that "it's nothing serious"... yet her behavior keeps getting more suspicious.

Little did you know you would find out what it is.

Cw. She has a sister.

Edit: I'm trying to fix it but it but for some reason it keeps tagging it as something it is not even close to. Moderation sucks ass
