Although you might be fooled by his tall height, B.A.P's Zelo reminded fans that he is still the maknae of his group by shedding tears during their 1st solo concert 'B.A.P LIVE ON EARTH SEOUL' on the 23rd and 24th. But for the majority of us who couldn't attend the concert, TS Entertainment finally unveiled the video of Zelo reading his touching letter to his parents.

Zelo shed tears while reading, "Mom, Dad, do you remember? That time when I was in 5th grade, I walked round-trip for four hours from Mokpo to Gwangju to go to a place where I can feed my passion to learn music. Joon Hong fulfilled his dream of becoming a singer and stood in front of mom, dad, and hyung with the new name of B.A.P's Zelo. Mom, Dad, I will respect you even more from now on. As 18 year-old Choi Joon Hong with the name B.A.P's Zelo will become a really kind son to be proud of."

Fans responded, "Although he looks like an adult, he made his debut when he was 16 years old and is now entering his sophomore year of high school. He must have had a difficult time adjusting", "Don't cry!", and "I respect Zelo's respect for his parents."
