Better Late than Single Season 2

Both are seasons of Better Late Than Single. You can watch one season without having to watch the other. They have the same concept (people in their 20s and 30s who have never dated interacting and going on dates to hopefully partner up) but a different cast.

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.
