On February 27 airing of Mnet's 'Perseverance Goo Hae Ra' Henry signaled a slow start to his relationship with co-actress Yoo Sung Eun with an accidental smooch on the lips! 

In the clip, Henry with his adorkable British accent is seen standing up for Yoo Sung Eun when she gets involved in a sticky situation after getting bumped into by a stranger with coffee. 

Henry comes to the rescue like a knight in shining armor and while he was trying to give her his jacket to cover the coffee stain on her shirt, another stranger bumps into Henry, causing his lips to land on Yoo Sung Eun. 

After the kiss, Henry gives a short monologue while placing his hand over his beating heart, "Why am I like this? Is it because I'm cold?" hinting at a possible love line between the two.

Check out the adorable video above.
