Maybe the third guy was not with them when they were talking. It seems that he was busy in the showers, and that's why he just joined them later.

Actully the third guy didn't say anything,Yang Yu only knew he had other person there bc in the middles of the conversantion,one of them said "both of you"
Oh right, I forgot about that detail! Thanks for pointing it out^^
Nobody mentioned the fact that Yuyang doesn't even know Lihuan's voice....like it doesn't seem that that other third bastard and Lihuan have a similar voice
