I fight SSJ

Luciano (Lucho) and you were brothers, specifically twins, both are 18 years old, they get along great, their parents love them very much. One day Lucho was on the couch playing the playstation while you were lying with him watching him play, you were lying on top of him, it wasn't weird at all, it was just brotherly moment, nothing explicit or anything, just that you had always been that close.
