Actor Kim Moo Yeol is one of the most loved faces on Korean screens at the moment, thanks to his role as the attractive education inspector Na Hwa Jin in the movie "Teach you a lesson".
In the film, Na Hwa Jin is not only an inspector who uses his power to protect vulnerable victims of bullying in the school environment, he is also portrayed as a lovesick man, carrying the pain and regret that has been buried for a long time about his late fiancée who is a teacher.
That feeling became an important motivation for Na Hwa Jin to join and devote all her heart to the Department for the Protection of Educational Rights.
Along with the attention paid to the film, the memorable real-life love story of Kim Moo Yeol with actress Yoon Seung Ah was also recalled by the online community.
What makes their story special is that it started from a confession of love when drunk and a "hand slip" on social media that changed their lives.
In the program "Knowing Brothers" in 2020, Kim Moo Yeol told it directly.
One night, after drinking alcohol and getting a little drunk, Kim Moo Yeol gathers all his courage to send Yoon Seung Ah a sincere confession of love.
The content of the message is said to contain affectionate words: "In the middle of the night, after drinking alcohol, I keep thinking about you. I want to hear your voice, want to see you. I sit alone writing these lines instead of calling, thinking that maybe you are already asleep.
You appeared in my life like a sudden variable, making me both confused, feel incomplete, and anxious about tomorrow. I thought you would be the one to perfect me, because before meeting you, I was just like my other half.
Good night. I'm talking too much and rambling today. What I really want to say is: I miss you so much.
However, instead of sending private messages to Yoon Seung Ah, Kim Moo Yeol accidentally publicly posted this content on social networks.

As soon as he discovered the error, the actor immediately deleted the post and hoped no one would pay attention. But then, the screenshot of the post quickly spread throughout social networks.
When confessions of love became a trend, Korean media also simultaneously reported that Kim Moo Yeol and Yoon Seung Ah were dating.
At the time of dating rumors, Seung Ah was filming and Kim Moo Yeol could not contact her for 6-7 hours, so he was afraid that his girlfriend would get angry and say goodbye.
Even, the actor said that he once thought about accepting a breakup if Seung Ah did not want to date publicly, because this happened when they had only known each other for 4 months.
However, Yoon Seung Ah reacted with sympathy and understanding. Instead of getting angry, the actress of "Moon Embracing the Sun" encouraged Kim Moo Yeol to accept the situation and publicize the relationship.
In February 2012, the couple officially confirmed their relationship with the media and fans, receiving many blessings.
In 2015, Kim Moo Yeol and Yoon Seung Ah held a wedding. By 2023, they welcomed their first son.
