Both have strangers who are non-celebs that cohabitate in one house and they date while doing missions. Both are reality shows with panels discussing the interactions of the non-celeb participants. Though Love catcher has an added spice since not everyone is in it for love... some for money. So the panel and participants have to guess, which makes the show more interesting.
So basically on Love catcher there are people that search for love and people that are just there for money. So you can decide in the beginning if you either came for money 50.000$(Catcher) or for true love(Lover) {+a couple ring, a trip together} You won’t know who's the “Lover” or the “Catcher” so it’s hard because the catcher needs to act like a lover to be able to get the money.. If you’re the lover you have to find another lover. If you are the Catcher you have to find a lover. Because lover+lover=love+trip+couple ring, catcher+catcher=nothing, catcher+lover=only catcher becomes money. If a Lover falls in love with a catcher sadly the Lover won’t get anything but disappointment and maybe even a heartbreak.. while the Catcher gets 50.000$ for being able to fool the people around him.
