Seo Joon Adorably Nags His Older Brother Seo Eon on "Superman Returns"

In a preview clip for the upcoming episode of “Superman Returns,” twins Seo Eon and Seo Joon enjoy a chocolate shaved ice dessert with their father Lee Hwi Jae.

After they dig in to the sweet treat, Seo Eon grabs a large spoonful only to hear his father tell him to take smaller scoops since eating too much at once could cause a stomach ache. Seo Joon then continues to nag his older brother and tells him he has too much.

He continues to be concerned with his brother’s actions and even frowns adorably.

The atmosphere gets lighter when the twins kindly feed one another. After Seo Joon feeds his brother, Seo Eon tries to reciprocate with a big scoop. However, Seo Joon is displeased and nags once again.
