Kim Muyeol and Yoon Seungah share adorable stories about their son, Won

'Teach You a Lesson' star Kim Muyeol and his wife, Yoon Seungah , just shared the absolute cutest stories about their son, Won.

During the broadcast, his wife Yoon Seungah also revealed that apparently, this tiny human already fully knows what**'protein'** means. In the episode of tvN's**'You Quiz on the Block'** that aired on the 1st, Yoon Seungah shared:

"Our son knows the word 'protein.' Since his dad eats protein every single day, he also knows that eating protein helps you build muscles. "

Recalling the time when Kim Muyeol was bulking up for a role, Yoon Seungah exposed him and said that he drinks blenderized chicken shake. She said:

_"There was even achicken-based shake. They even have a strawberry-flavored one. Watching him drink it made me think**'Wow, he really goes through so much.' I guess that's why Won naturally came to associate protein with muscles.** " _

Apart from learning some advanced vocabularies like 'protein,' Won is also super protective of his dad. Kim Muyeol shared a hilarious new trend that has taken over his son's kindergarten class :

"My son just turned three recently. One thing that's been making me especially happy lately is that there's a new catchphrase going around his class: 'Won's dad.' "

Kim Muyeol explained that when he visited his son's kindergarten, one of the kids spotted him and excitedly shouted, "Won's dad!" Sparked by a wave of jealousy, Won immediately shouted back even louder,"Won's dad!' to assert that Kim Muyeol was his father. He added:

"Thenit spread like a competition , so now whenever I go to pick him up, all the kids in the class would shout, 'Won's dad!' "

Having publicly confirmed they were dating in 2012 , Kim Muyeol and Yoon Seungah got married in 2015. Eight years later, they welcomed their beloved son, Won , in June 2023.
