On May 9 episode of KBS' television show 'The Return of Superman', Geon-hoo made everybody's heart melt with his thoughtful behavior.

Na-eun danced to K-pop artist IU's latest track 'LILAC' with other boys and girls who came to the class.
Since Geon-hoo enjoys dancing, he could not take eyes off them dancing together.
Na-eun noticed this, and asked the instructor if Geon-hoo could join them; the instructor willingly agreed to it.

He immediately went back to Jin-woo and gave him a cup of water.
As Geon-hoo tried to join the group, Jin-woo spilled water on the floor.

While doing so, Geon-hoo's eyes were locked on the boys and girls who were excitedly dancing.

So, Geon-hoo ended up dancing by himself, but he did not complain about the whole situation for a second.
Upon watching this part of the episode, 'The Return of Superman' fans commented, "Wow, Geon-hoo's all grown up now.", "This is so touching.", "He's such a good hyung." and so on.
