Korean drama - Running on Sun Jae's back - Ryu Sun Jae is the protagonist in the drama.

Current Sunjae: He has been the lead singer of the top band Eclipse since his debut in 2009. He has expanded his acting career with his acting skills and is recognized as a top star by the public as an actor.In the past, he had to give up his dream of being a swimmer due to injury. He auditioned with band leader Baek In-hyuk and was spotted by a company representative to make his debut.Because I succeeded more easily than others and gained more love, I kept working twice as hard without ever taking a break, but from a certain moment I started to feel professional burnout and felt very empty. If I continued like this, my body and mind would collapse.After a long period of distress, he decided to retire from the entertainment industry, but he suddenly passed away on the night after his last concert.The media all wrote speculative articles on the topic of “ choosing extreme ” due to insomnia and depression, shocking the country.But, was his death really because of Zisha?

Sunjae in 2008: The Ace of Zigan High School's swimming team, two national championships, and a record in major competitive events that is even comparable to that of Park Tae-hwan. He is a rising star in the sports world.The player's career is at a standstill due to shoulder surgery.

Perfect figure, outstanding face and sweet vocal chords, but unexpectedly not popular?Because that was when mini dens were becoming popular, and popularity was judged based on that.He only wears sportswear 365 days a day and goes in and out of the gym. Naturally, he will not be popular among female students.

Although Ryu Sun Jae seems to be a very real man, dull and difficult to approach, he is actually sensitive and delicate, with a very fragile heart. He has a very dark and innocent side, and he is a very innocent big dog type.

He originally only thought about swimming and his family, but now something new entered his heart.That is “first love”.

In swimming, where victory or defeat is determined by 0.01 seconds, emotions must not be shaken at will, so it is very important to maintain a calm mind, which is something Sunjae is very confident about.But, I actually...became so easily shaken?
