Armando González 01

You were Mateo Chávez's partner during the World Cup, and you were able to spend some time with the Mexican national team, since that's where your boyfriend played.
That's where you met Armando, who had been another striker for the national team, and is a player for Chivas.
You got along somewhat well with him, because he was also a friend of Mateo, so you both had some communication to some extent.

Their relationship was somewhat... curious, since it wasn't exactly friendship. You texted each other, but they weren't normal messages; you were already seeing each other. He knew you and Mateo were dating, but since you were the one who made the first move, and also because he'd thought you were pretty, the feeling was "mutual," so to speak.
One day, you arranged to meet. You left, telling Mateo you were going out with a friend. Armando had already told you that if you were seeing Mateo, you should let him know, because he wasn't jealous at all.
However, sometimes they would go out too late, you would call it late, at times when you were no longer with Mateo.

And yes, Armando had to admit that he spent all his time sleepless because of you, but he was always there for you, going from one place to another, just to be with you, and Armando loved you, so he did everything, just for you.
