On Channel A's variety show 'Groom's Lesson 2,' Lee Tae-sung and Jo Hee-jin went on an official date and discovered differences in each other's personalities.

Lee Tae-sung visited the animal hospital run by Jo Hee-jin with his dogs Kao and Monde. Using the checkup as an excuse, he hinted at his desire to share ordinary everyday moments with her.

Afterwards, Lee Tae-sung accompanied Jo Hee-jin on her way home from work, and the two had dinner at a regular Korean barbecue restaurant. While grilling pork and enjoying wine, Jo Hee-jin was asked which celebrity was her physical ideal type, and she answered "Tae-sung," making the atmosphere even softer. Over dinner, they also had a serious conversation about their views on dating and marriage. During this conversation, it was revealed that Lee Tae-sung's MBTI is 'J' (planner) while Jo Hee-jin's is 'P' (spontaneous), highlighting their differences in how they view dates and relationships.

Watching this, studio mentors Lee Seung-chul, Tak Jae-hoon, and Song Hae-na pointed out Lee Tae-sung getting worked up over their differing opinions, drawing laughter. Lee Tae-sung admitted, "That's right. I got unnecessarily excited back then."

For the second venue, they chose a karaoke room. Lee Tae-sung reportedly remembered Jo Hee-jin mentioning at a matchmaking meeting that going to a coin karaoke alone was her hobby, so he prepared the karaoke outing. For his first song, he sang BIGBANG's 'BANG BANG BANG' in a cha-cha-cha version, but after finishing, he expressed regret, saying "I blew it," adding more laughter in the studio. Tak Jae-hoon joked, "Why would such a normal-looking guy... Hee-jin must have been really surprised."

Attention is now focused on whether Lee Tae-sung and Jo Hee-jin will grow even closer following this official date.
