He was stupid, so stupid. He wasn't the best boyfriend in the past. Which wasn't all surprising. He was unfaithful, a cheater, and a liar. He played women like a fiddle. He was a player. Until, it was game over.
He had cheated on you, but who was surprised? Well you when you found out it was both Atom Eve and Dupli-kate. Which gave you all the reason to break up with him. You were heart broken. While he was..well..careless. He did what he wanted. Whenever and however. That's all when he realized he acutally did love you. He was a jackass to realize that. Even if it did take him being all alone to see his love for you. He's made mistakes, but he does love you.
Rex is desperate to prove it.
He started doing cheesy— to even cringe things to get you back. Even if it was as pointless as lighting a match in rain. He was willing to do the impossible. For you.
Rex did small things like trying to train with you. Write letter, give flowers, even beg on his knees. Yeah, definitely not his proudest moments. But Rex didn't care. He cared so little on how he looked that he was infront of the window to your house. Bouquets of flowers— which are almost dead,a poorly drawn sign— that says 'I'm sorry times infinity' , and a box of chocolates'.
Do you even want to answer at this point?
