Jang Woo-hyuk and Oh Chae-i confirmed that they are special to each other and had a serious conversation on the September 10th broadcast of Channel A's "These Days' Men's Life - Groom Lessons." The two enjoyed a dream amusement park date, deepening their understanding of each other's feelings.

Based on the experience of eating the lunchbox Oh Chae-i brought on their previous kids' cafe date, Jang Woo-hyuk prepared a lunchbox with food he made himself and gifted it to Oh Chae-i this time. Using peas grown by his mother to decorate the lunchbox with a heart, Jang Woo-hyuk said, "This is the first time in my life I've packed a lunchbox, and it's also the first time I've made a heart."

At that moment, Jang Woo-hyuk's friend of 30 years called and asked, "It looked good? Your expression seemed serious. If you're dating seriously, it means your heart is really into it. So, are you thinking about the future as well?" Jang Woo-hyuk replied, "That's right." This indicates that their relationship is developing beyond a simple date into serious feelings.

Meeting Oh Chae-i at the amusement park, Jang Woo-hyuk complimented her, saying, "You look so beautiful today," and Oh Chae-i said, "I'm actually very nervous and excited. Going to an amusement park has been my dream if I had a boyfriend." Shim Jin-hwa expressed surprise at Jang Woo-hyuk's public date, saying, "What's really surprising is that H.O.T.'s Woo-hyuk oppa is confidently going on a date in such a public, crowded place."

The two enjoyed their amusement park date wearing school uniforms and couple headbands. After riding the attractions, Jang Woo-hyuk revealed the lunchbox he prepared, and Oh Chae-i expressed her emotion, saying, "I think this is the first time I've received a lunchbox, except for the ones my mom packed when I was young." Jang Woo-hyuk tried to flirt by saying to Oh Chae-i, "You look really pretty when you eat," and Oh Chae-i, though flustered, happily said, "I feel really good."

Later, while experiencing the haunted house, Oh Chae-i got scared, and Jang Woo-hyuk held her hand for the first time, saying, "Just stick close to me." Jang Woo-hyuk found a stage inside the amusement park and explained that it was a special place that opened the opportunity for H.O.T.'s debut, saying, "This place is very meaningful to me. I wanted to come here with someone special." Oh Chae-i responded, "Thank you for bringing me here and sharing this memorable place. It feels like I'm sharing your life."

Riding the carousel, the filming location of H.O.T.'s hit song "Candy" music video, Jang Woo-hyuk asked Oh Chae-i, "Shall I hold your hand?" and she took his hand. Jang Woo-hyuk suggested greeting the people watching them and indirectly confessed by saying, "Now, because you're my girl." Afterwards, the two took a sweet couple photo in front of the carousel.

The second date course was a cocktail bar prepared by Oh Chae-i, offering a panoramic view of Seoul's landmarks. Watching couples doing wedding photoshoots nearby, Jang Woo-hyuk talked with Oh Chae-i about their dream wedding. They agreed that life after the wedding is more important than the ceremony itself.

Jang Woo-hyuk asked Oh Chae-i if she had recently talked about him with Lee Da-hae, who arranged their blind date, and Oh Chae-i said, "We met once separately. Da-hae unnie told me to definitely watch the show where Woo-hyuk oppa's mother appears," adding, "I think I saw a family-oriented side of oppa. Seeing how he treats his mother, I imagined what it would be like if he started a family."

Oh Chae-i revealed that her first impression of Jang Woo-hyuk seemed cold, saying, "He is cheerful, bright, and positive, but I felt a solid wall inside. That was just the first impression. But the more I meet him, the more I see new sides and his warm nature," expressing her fondness for him.

Jang Woo-hyuk confessed, "I actually had a similar thought. When we first met, I wondered, 'Is he a family-oriented person?' His appearance was flashy, so it felt far from family-oriented, but seeing him take care of his nephew, I thought he was really a good person. Looking back on today, I realized that Chae-i is a very special person to me."

Jang Woo-hyuk asked if he could get an answer to the question he asked during their last date about whether she was serious about dating him, and Oh Chae-i said, "I also really like dating seriously, just like you think. But as I said before, I want a relationship based on marriage, not a casual one, so I have to be more cautious. So, how about we take more time to get to know each other carefully? Because I am serious about you, I feel this way."
