Heo Youngsaeng 허영생 is the main vocal of SS501 and the leader of Double S 301.
Youngsaeng was born on Monday, November 3, 1986.
Like SS501’s leader, Hyunjoon, he was born in the Chinese Year of the Tiger. He’s a Scorpio. Youngsaeng, Jungmin, and Hyungjun’s blood type is O.
At a height of 178 cm or 5'10", he’s the shortest member of SS501. He’s shorter than the three tallest members, Kyujong, Jungmin, and Hyungjun, by 3 cm.
He attended Dong Seoul University and Hyundai High School.
He began as a trainee under SM Entertainment, making him close with members of TVXQ and Super Junior. He later joined DSP Entertainment and debuted as a member of SS501 on June 8, 2005.
He hosted SS501′s Youngstreet on SBS with fellow member Jungmin beginning on May 1, 2006. He had to part with the program that August due to his throat condition. He had laryngeal surgery; it took months to rest his voice and recover.
In 2008, due to Hyunjoong filming the drama “Boys over Flowers” and Jungmin performing in Grease, SS501′s upcoming album was pushed back to July 2009. As a result, the three remaining members formed a sub-unit with Youngsaeng as their leader. The unit group was initially named “Triple S” but they changed it back to “SS501″ out of respect for the group always being one. They released a special project album, U R Man, on November 25, 2008.
Youngsaeng composed and wrote his solo song, “사랑인거죠 (Is it Love?),” also included in the special project album. He wrote the song during SS501’s promotional activities in Japan in 2007. He’s the first member to have both composed and written lyrics for a song.
After promoting “U R Man,” the sub-unit promoted “내 머리가 나빠서 (Because I’m Stupid)” from the “Boys over Flowers” soundtrack. They won the Song of the Month award for February at the 32nd Cyworld Digital Music Awards on March 28, 2009, with about 110,000 downloads.
He debuted as a solo artist in May of 2011 with the mini-album Let It Go. That same year, he took on the role of D`artagnan in Three Musketeers. In 2013, he appeared in the musical Summer Snow.
On October 20, 2013, days before beginning his military service, he had his first and farewell concert for his fans. It was the first time in three years for SS501 to perform as a full group. He fulfilled his military service as a conscripted policeman in July of 2015.
Youngsaeng plays the piano.
His hobbies are playing computer games, playing basketball, and taking selcas.
He was given the nickname “Shy Prince” because he gets extremely quiet on camera. Among the members, he is the best at impersonations. Among kids under 10, he’s the most popular member.
His ideal breakfast is milk and cheese. His ideal date is going for a drive. His favorite parts of his home are the balcony and his bedroom. His favorite subject is English; he doesn’t like math. He loves roses and his favorite animals are dogs.
He takes good care of his hair and is very conscious about it. The first thing he does upon waking is drink water.
He describes himself as a mystic person. He has a lot of respect for people who are passionate and excel at their work.
There’s some confusion over whether he was born in Gochang, Jeollabuk-do and grew up in Gwangju, Gyeonggi-do, or the other way around.
