Hae In is making his comeback this year in the Netflix series D.P. and he will playing a soldier once again. The twist? He's set to catch other soldiers! So, to prepare your ~feels~ for the release of his new drama tomorrow, here are 12 things you *really* need to know about him.

*Interesting* Facts About Jung Hae In

1. He is 33 years old.

Jung Hae In's birthday is on April 1, 1988, which makes him an Aries. Those who are under this sign are driven, generous, and VERY honest. Like his character in While You Were Sleeping, Hae In said that he's straightforward when it comes to expressing his emotions.


Although he doesn't have any stage name, Hae In has a nickname. He's dubbed as "Milk Man" because of his superior genes. Here's proof: According to his former makeup artist, Hae In doesn't need to use a lot of cosmetics because of his great skin and perfect eyebrows. We totally agree!

2. He came from a wealthy family.

The Jung family is a well-known clan in South Korea: Hae In's great grandfather is Jung Yakyong, an influential figure in the Joseon era who is recognized for his written works on philosophy, science, and the government. As for Hae In's parents, they run a hospital in SoKor. Since they're often busy, he was raised by his grandparents and he would look after his younger brother when as a child (more on his dongsaeng later). 

3. Jung Hae In initially planned to study biotechnology.

In college, he was already set to apply as a biotechnology major in a university but guess what—Hae In applied under the Broadcasting Entertainment department instead. He kept this a secret from his parents. When they found out about his shift in courses, Hae In's eomma and appa were not in favor of his decision. However, they eventually accepted it, and even attended his school performances saying: "You were really great. You can continue doing it." Awww!

P.S: He was an introvert in middle school and high school but he became more outgoing when he entered college.

4. He realized he wanted to become an actor when he enlisted in the military. 

Hae In's turning point in life was when he became a part of the army at the age of 21. He describes those two years in the military as a "precious time" for him because he was able to realize that acting is what he truly wants. Hae In was *so* determined to become an actor that he lost 12 kilograms while in the army to prepare for this ~new~ career path. During his 2019 fan meeting in Manila, Hae In said he can't imagine doing anything apart from being an actor: "I'll always be an actor, no matter what."

5. Jung Hae In's first small screen appearance is in a music video!

I was today years old when I discovered that Hae In was featured in AOA Black's "MOYA" MV in 2013! K-pop stans, did you spot him here?


The following year, he made his *official* debut in the K-drama, Bride Of The Century, where he sported a blonde hairstyle.

Hae In started with supporting roles and he eventually became the leading man in K-dramas. This includes Something In The RainOne Spring Night, and A Piece Of Your Mind.

He has also starred in movies, like The King's Note, Tune In For Love, and Start-Up, among others.

6. He learned a lot of things from the book The Subtle Art of Not Giving A F*ck.

Just like the rest of us, Hae In also goes through bad days. In the past, some people would comment about his late debut (he started his career at the age of 26) but according to him, he is not worried about it: "I don't expect to rise to stardom for a moment. I want to look at it slowly and for a long time and climb one step at a time." 

Whenever he is struggling, Hae In would say "I can do it!" to himself, and he would apply the lessons he learned from the book The Subtle Art Of Not Giving A F*ck. An example: To stop comparing yourself with others and be grateful for what you have instead. BRB, buying a copy!

I just like everything he does. He’s a good person."

On top of being a gentle soul, Hae In loves giving presents to the people he is close with. One of them is his long-time manager, whom he gifted with a foreign car. He would also show his support to other actors by sending a coffee truck to their filming set, including Cha Eun Woo.
