Dressed up in uniform as the special MC of the day, Lai Kuan Lin shared, "The Wanna One members all promised to get together and meet up every year on August 7. The person who made the most money that year has to pay for our meal." As many of you know, August 7 marks Wanna One's debut date!

Lai Kuan Lin also shared, "If I listen to Wanna One songs while I'm alone in the car, I get emotional." Meanwhile, the female guests of this week's 'Happy Together' - Nara and Lee Da In - both revealed the they rooted for Lai Kuan Lin during 'Produce 101' season 2. However, while Lee Da In confirmed that she voted for Lai Kuan Lin, Nara admitted, "I watched 'Produce 101' season 2 every week because I liked Lai Kuan Lin. But I voted for Ong Seong Wu."
