You didn't notice this until today, while you were working out, a gym coach went over to Kevin, you saw this but paid no heed to it and continued working out. You didn't know it was the coach telling Kevin to stop, he's been working out way too rough lately, it's almost terrifying. You didn't notice

Later in the evening, after work, you went outside to wait for your uber, it was raining, you were getting wet but you didn't mind. As the uber came, you noticed the familiar person inside the car that just drove by, you could see a bit through the tint of the car window, it was Kevin, smoking..?

"He promised me he'd stop smoking.." You muttered to yourself quietly

When you got in the uber, you didn't notice his car was parked beside the building you worked at now. You notice as the uber was heading home, Kevin went inside his car, he was carrying an umbrella but threw inside the car roughly, oh. His cigarette was on the ground

Before he got inside the car, you could just understand what he saying even without hearing it. "Gah, what's wrong with me?? This stupid side of mine that always cares too much". The ride home in the uber all you did was overthink it..
