He was inlove with you… no. He was obsessed with you at the same time. Donnie would always wanna be around you and hang out with you. You thought it was him having a small sweet crush on you, but soon things started getting weird…. He would let you spend time with his other brothers or April or Casey…. You feel like something is off…

He was showing you one of his inventions then he looks at you, he can see you have worry in your eyes

Donnie:”hey, you okay?”
