Even romance reality newcomers are thrilled—analysis begins with such energy that first-meeting awkwardness vanishes instantly

While Maruyama Rei has watched the Japanese version and Yamashita Kouki is familiar with the 'HEART SIGNAL' series, Miyako is a first-time viewer, admitting, 'I can't watch romance reality shows alone.' Despite it being their first time meeting, the trio instantly clicks as the program begins, launching into an energetic and passionate analysis session. Set against the backdrop of a -9°C Seoul winter, the story of six participants meeting captivates all three with its subtle atmosphere and the mature charm of the cast.

'It's intentional too?!' Studio erupts in laughter over analysis of Woo-yul and 'home-cooked meal' talk

Male participant Woo-yul is quiet in group settings but becomes talkative one-on-one. Maruyama notes, 'He's quiet, but he really comes alive in one-on-one conversations,' and Yamashita agrees, 'He starts talking a lot.' Miyako sharply interjects, 'Wait, is that intentional?!' When Yamashita—revealing he's similar to Woo-yul—accidentally blurts out, 'Well, it's partly intentional... and also, it's just easier to talk one-on-one...,' Miyako instantly fires back, 'It's intentional too?!'—showcasing seamless comedic timing despite being strangers. Maruyama praises Woo-yul's ability to 'say exactly what you want to hear at the right moment,' calling him 'pretty addictive,' causing Miyako—who initially supported So-won—to admit, 'I'm totally swayed now.'

The studio erupts again during the shared kitchen cooking scenes. Conversation veers into personal anecdotes, with Miyako sharing her mala soup story and Maruyama passionately declaring, 'When I’m served a slightly messy “guy’s cooking,” I just think, Life is great!' When Yamashita says he'd prefer a homely 'chikuzen-ni' (simmered dish), Maruyama instantly retorts, 'If chikuzen-ni shows up first, I’d get weirded out,' creating a hilarious moment worth watching.

Final episode approaching! Catch up now before it ends

The first episode concludes with a shocking twist that prompts Maruyama to exclaim, 'This is hell,' and Miyako to react, 'This is intense!' The ending fuels heated speculation in the studio about future pairings—'Who will end up with whom?'—as romantic signals intensify. 'The day is so packed!' 'I want to keep watching!' The trio’s excitement reaches its peak.

U-NEXT will stream the final episode on Tuesday, July 28, 2026. Don’t miss it.
