i don't think that sugarB could be interessed because:
the guy is just a guy who she's fucking, is not a regular bf and as you see, they don't have a regular sex
SugarB is not sure to stay in barcelona for a long time. she was thinking to go back in italy for a seasonal job
she's likes to stay at home , alone with her laptop and her music. i think could be boring.
i'm not sure, but maybe rlc want to make her a regular tenant and put microphones in her room.
