What do you think of someone I know and someone else falling in love with each other within seconds when they just heard each others voice?

A guy I know and his wife fell in love with each other within seconds through talking on audio on a vídeo game playstation of the of the first moments talking to each other. They haven't even seen each others faces yet. They are still obessed with each other, became boyfriend and girlfriend. Eventually married. Is it romantic love or just obessed with each other? They lovebombed each other always.
