Complete Information About Singer Ga-in (Profile, Facts, Debut, Solo, and Boyfriend)


Ga-in Couple with Jo-kwon on MBC’s We Got Married

On October 3, 2009, Ga-In and Jo-Kwon became a couple in the Chuseok special edition of We Got Married, along with couple SG Wannabe’s Lee Seok-hun & host Kim Na-young. Since Ga-In and Jo-Kwon had the highest rating during the show, they were announced as a permanent couple.

They both get huge attention from viewers because of their romantic interaction during the show. Jo-Kwon was funny, lovable, and cheerful, and also hyperactive and talkative. On the other hand, Ga-In had beauty, cuteness, was sexy, and was also skilled at cooking. She’s kind of person who thinks one step ahead and hates to lose. She was older than Jo-Kwon, to reveal her opinion, sometimes she hesitated and felt awkward during first episode. One of her weaknesses was never knowing how to respond Jo Kwon’s teasing.

The fans gave the couple a special name, “Adam Couple”, because they are so petite. During We got Married, they, as Adam Couple, released a duet called “We fell in love”, which got appreciation on KBS Music Bank. This beautiful couple had their first kiss in Bali during their wedding photoshoot. This couple also had the longest virtual marriage in We Got Married, which lasted one year and three months.

There is an episode when Ga-In and Jo Kwon are shopping to cook for both 2AM and the Brown Eyed Girls. The show’s production staff thought that would be nice if they had both groups come together. Ga-In and Jo Kwon cooked for everyone at the 2AM apartment, and both Seulong and Changmin were playing baseball on the Nintendo Wii. The Brown Eyed Girls showed up with toilet paper as a gift ,and they ate together. The next episode was also entertaining, because they did a cooking and bowling competition between 2AM and the Brown Eyed Girls. Such an entertaining and cute couple!

Ga-in’s Love Story and Boyfriend

Ga-in used to have a relationship with Joo Ji Hoon, a South Korean actor who became popular in the K-drama Princess Hours. They had been together as couple for three years before suddenly ending the relationship. Joo Ji Hoon’s label, Key East Entertainment, and Ga-In label, Mystic Entertainment, didn’t immediately issue statements about it, since they needed confirmation from their artists first.

Before they started dating, they had been friends for eight years. They become closer after shooting Ga-In’s music video titled “Fxxk U”. The video showed an intimate and romantic relationship. No one expected it when, not long after that, they become a real couple like they were showing on the music video. Their agencies confirmed the relationship.

Ga-in’s Controversy

Ga-In and her boyfriend’s breakup happened after the rumor of her boyfriend offered her marijuana. Ga-In confessed on her Instagram account multiple times about this incident. She admitted that she did not take any of marijuana, which was offered by a friend of Joo Ji Hoon, her ex-boy friend.

On her Instagram account, she uploaded the following caption:

As you all may know, I’m the girlfriend of a previous junkie (Of course, as far as I know, he has received all appropriate punishment and now lives diligently). But even if I’m Joo Ji Hoon’s girlfriend, [Park Jung Wook shouldn’t have done this]. His friend Park Jung Wook offered me marijuana. Yes, I almost gave in, since I wasn’t in the right mental state. But I’ve been clean all my life, and I won’t do marijuana until it becomes legal. [I don’t need marijuana], I’m already injecting legal morphine. If you’re butt-hurt, smoke [marijuana] and go to jail, or be really ill and take morphine. You’re a dead man if you recommend me to do marijuana.”

She also uploaded screenshot about the evidence, which is translated below,

Park Jung Wook (henceforth ‘P’): What did I do to make you do this to me? Let’s talk.

Ga In (henceforth ‘G’): Weed

P: I said I didn’t.

G: You offered it to me.

P: I told you I was only trying to find a way to make you feel better.

G: You’re backing out.

P: I’m not backing out. It’s the truth.

G: You wanted to make me feel better so you offered me weed? And you’re saying that’s all a joke?

P: I was trying any sort of method to make you feel better.

“I don’t need to shoot ads. I don’t care about my image. I have enough money for me to use and eat until I die. I’m going to voluntarily take a drug test every three months.”

Later on, Ga-In talked about her mental treatment, but she was fully aware about that and not taking advantage by using marijuana. She made the brave statement, “Yes, I’m a mental patient undergoing treatment, and I’m not ashamed of that. I’m going to be cured. I will tell you one by one why I’ve gone crazy, even if it gets me in jail and even if it gets me killed.” Cool Ga-In!

After that, she deleted it all the posts she has been made about this controversy on her Instagram.
