Broadcaster Lee Sang-min carefully captured the emotions of the Signal House residents during the final episode of Channel A's 'Heart Signal 5,' drawing deep empathy from viewers. In the latest broadcast, he observed the residents' final conversations with a warm perspective, naturally guiding the atmosphere of the program.

First, regarding Park U-yeol showing his honest side in front of Kang Yu-kyung, Lee Sang-min said, "Seeing him let everything go, I think I felt, 'So this is what happiness is.'" Watching their conversation, he evaluated, "The fact that I changed because of someone I like is a 'great love.'" Later, when Park U-yeol and Kang Yu-kyung chose each other as their final picks, his eyes reddened, and he said, "I don't even cry at most dramas!" bringing laughter to the set.

Lee Sang-min had previously predicted that Kim Sung-min's love interest would be Kang Yu-kyung. He mentioned, "What caught my attention was when Sung-min said his last word to (Kim Min-ju), which was 'thank you,'" showing sincere support for the residents' final choices.

Sharing his thoughts on the conclusion of the show through his agency, Lee Sang-min said, "While I watched past seasons for the fun of peeking into romance, this season made me reflect on my own experiences of loving someone. The depth was exceptional, and I was moved every time I watched it." He then cited 'unwavering purity' as the charm of 'Heart Signal 5.'

He explained, "While recent dating programs are becoming increasingly sensational, 'Heart Signal,' from season 1 to 5, felt like a novel-like youth drama." He added, "The fact that even a small gesture like holding hands or interlocking fingers can sufficiently deliver heart-fluttering excitement and the desire to love to viewers is a testament to the production team's directorial expertise and skill," highly praising the crew's abilities.

As the show dealt with MZ generation dating, he also addressed the universal empathy that resonates across all generations. He analyzed, "It's just a difference in place and time; the way the MZ generation loves began with the same purity that all generations could relate to," adding, "The conflicts, love triangles, and other elements were things everyone could feel, which made it even better."

He also expressed his affection for the Signal House residents. Lee Sang-min shared, "I found myself rooting for Kang Yu-kyung's love line, as she controlled Park U-yeol's wavering heart and kept things thrillingly suspenseful," and added, "When Kim Min-ju and Kim Sung-min's conversation missed each other, I felt so sorry and upset for Min-ju's position."

Finally, he showed deep affection for the program, saying, "I was once again moved by the fact that 'Heart Signal 5' was able to capture deep storytelling and beauty in a short-form Shorts market."
