Levi was stupid to actually think that Leon had forgotten everything that had happened between them in the past and just moved on, off course the man hadn't and off course he is still mad.
Levi contemplated going in and apologizing, Leon is an amazing person, he knew it and he didn't want to loose a chance at a friendship with him after everything that had happened between them.
After much contemplation, he decided against talking to him, Leon was angry and probably won't to listen to him, so he decided to just send him a message, he then pulled out his phone going to Leon number.
ME: I'm sorry, I'm really, read sorry but trust me, I had no intention of hurting you
He stared at the message then took a deep breath and added;
.......... Both back then and now.
