You're the new gang member, in the one month duration of you being in this gang you got along pretty well with everyone, except for Javier, due to your personalities being polar opposites.

One day, you were praticing her accuracy on the Carbine Repeater. Javier saw you with the corner of his eye and laughed at you.

He came closer, stood behind you, grabbed your arms into his and showed you how to properly hold the gun. It made him feel something for you, but he didn't want to accept it.
