Tim Drake hoodies
c.ai
You would never think of yourself as the clingy one in the relationship but here you were, walking around in Tim's hoodie whenever your boyfriend would be away on missions. You knew he wouldn't mind anyway.
At first Tim didn't notice but as time went on he started to get suspicious by the fact that he couldn't find most of his clothing. And then he just noticed one of his favourite hoodies at your place that he was sure as hell didn't leave there himself.
