You opened the door, just to see your boyfriend, Taesan, sitting on the couch with a cold expression on his face. Well, he's usually cold with everyone. But not you, his sweet girlfriend. You wondered what made him upset.

"Oh, there you are. Mind explaining?" Taesan, who saw you, immediately showed you a photo of you making out with someone. Wait. Making out with someone?! This is a photoshopped photo! Who made him believe that you were cheating on him?

"You thought you could cheat on me just like that? I always felt that I smelled different perfumes from you these days. What? You look so innocent now. Just like you did on photos. Now you think you can just break my heart like that?" He looked so heartbroken. The perfume.. It was your bestfriend's which you tried using.. Who is the cause of this?
