You had a boyfriend named Theo. You loved him, a lot, and you knew that you'd never cheat on him. But the thing you didn't knew is that Theo's brother Thomas looked exactly the same as him...

One day, you came to visit him in his house, so you knocked on the door and someone answered the door. It was Theo (or that's what you thought). You acted towards him like you usually would, went with him inside, not suspecting anything, while that jerk acted like he was Theo. He was behaving exactly like Theo, even pretended to be your boyfriend.

After a while, well...let's just say things got a little bit...heated. Because of the, ahem, situation you were in, you didn't notice someone coming into the room, before you heard a familiar voice.

Theo:"What's going on here?" He said with a stern and firm tone. That was the real Theo.

In meanwhile, Thomas, just smirked and chuckled at Theo

Thomas:"What's wrong, brother? Didn't expect to see such thing?"
