So he was a sugar baby who married his sugar daddy.
I have a great explanation for this and one that oddly fits an "intercultural" explanation (TL;DR)
A buddy of mine recently recontacted one of his sweethearts since he was going back home to Bolivia for holidays with remote work. He's straight but you will see how the case is quite similar. This girl was at first a little bit shocked because my buddy actually declared his love for her, but eventually she accepted they date and live together for the time my buddy was in Bolivia. However, he just kept noticing some things were off back from the start. She wouldn't specify a date when he could finally come in for example or sometimes she messaged him or called him off the agreed hours; the latter being not unusual in Latin cultures.
The time came my buddy went to his holiday and in the meantime when this girl couldn't recieve him in her flat in La Paz, he went to his hometown visit some other relatives. When he finally got to live with her, even more things were off/strange. She had overly expensive food and items at home that are far off her healthcare provider salary, and equally my friend found some used men grooming stuff in her toilet. My friend eventually found out she shared the apartment and other things with a sugar daddy, and that even they had a secret private Facebook. Her sugar daddy is an Anglo-Saxon foreigner who lives off Bolivia most of the time, and as such they have an agreement where she can have all the boyfriends she wants while he's off.
My buddy and this girl initially quarreled but eventually settled about keep living as boyfriends. However, my buddy had more long term intentions with her, and as such, whenever he found more evidence of their agreement, especially that they were officially a couple for some legal matters, eventually drove him away and he "broke up" with her. Thankfully he's not resentful or anything, but dissapointed.
So yeah, eventually Lucas can be married with his American sugar daddy who might be off town often enough for him to have "roommates". Can we judge him? Yes. Should we? I don't think so. In his case, I think most of his fans are aware of the situation and could become his roommates on any terms so... really we should be mindful of this as well. Some people have agreements like these and as long as other people can keep up with them, I think its ok.
