Both are Korean variety dating shows, but their concepts are different. BLTS has contestants that have never dated all living in a house together for several days, going on multiple dates until the final pairing. MSR has sets of male and female siblings all live together in one house for several days, also following the same events until the final pairing. Both hold off on mentioning age or background until further in the show. Both use phones to pair up with others, although MSR more so because there’s daily ratings of potential partners.
