It's really not good and I just wrote without any idea but here it is

"Lilly?"

"Lilly??"

"LILLY. STOP DOING THAT"

Lilly laughed at Izzies face. Since 20 minutes they were playing an old videogame on the TV. Izzie's only goal was to get passed the first level while Lilly constantly did stupid stuff like hitting her with her ellbow, kissing her cheek, tackeling her, literally everything to distract her. By know it was the middle of the night. And they still weren't past the first level. By now Izzie was really sure that Lilly was actually good at the game and just wanted to spend more time with her. And it was really working.

Several minutes later they heard foodsteps and Jamie walked down the stairs. "Why... are you still awake?", he tiredly looked at the screen. "Hey you are still playing-- This is still the first level. Why are you still on the first level. It's really not that hard. Do you need help?" "We can do that Jamie boy.", Lilly grinned up at him and lovingly smiled at Izzie. 

Jamie uncomfortably looked between them and just stood there without saying anything. Lilly smiled at him. "You should go to sleep, Jamie. It's late and you just fixed your sleep schedule.", Jamie just looked at her for a few seconds. Neither Lilly nor Izzie saw how Jamie looked at Lilly. They never saw. Or they didn't care. He just slowly nodded and went to his room. He laied down and starred at the ceiling. Of course he was happy for them. He was happy for Lilly. She found someone that made her happy. He looked over at an old picture of them together. When he was younger he had a crush on her. And then they grew older. Now she was really happy. Sometimes he just wished that it was him instead.
