Ex’s description: Jung Won-gyu is a capital-T personality through and through. He comes across as rational, composed, and a little aloof, so he may seem hard to approach at first. Get to know him, though, and you’ll find a warm, adorable side. He is not very expressive, yet he lingers nearby like a little cat. He also has an unexpected soft spot for cute things, especially small animals. Calm and comforting like a lake, he gives people a sense of security and once made his ex think about marriage.

Even his occasional clumsy moments are endearing. Honest, warm, and kind, he is always busy caring for others and not very good at caring for himself. That made his ex feel for him, and they hope he finds someone here he can lean on.

Looking back, though, they realize they were simply both too young and immature then. Jae-hyeong also looks especially cool when he dances, so give him a chance to show that side of himself!

Ex’s description: Park Ji-hyun may look cool and distant, yet she is actually adorably scatterbrained. She is always leaving things behind and getting food on herself, and even those moments are cute. Her favorite food is fried chicken, and eating something delicious can instantly lift her spirits when she’s feeling down. She’s cheerful and enjoys being around others, while also having a deep inner world; even her small gestures and words carry meaning. Calm and principled, she never does anything she can’t take responsibility for. Her ex considers her the most thoughtful person they have ever met.

Transit Love 4 female cast member: #5 Park Hyun-ji 박현지

• Age: Born in 1997 / 29 years old
• IG: @hyundipark

Ex’s description (by Seung-yong): Hyun-ji is more honest about her feelings than anyone, so she never leaves the other person confused. She is shy and quiet around people she has just met, to the point that she cannot even make eye contact. Once she becomes close to someone, though, she loves chatting and acting cute, freely doing silly, adorable things and often creating little memories just for the two of them. What she wants most in a relationship is simple: emotional expression and care from the other person, along with a shared emotional connection. Hyun-ji has a childlike purity and candor, with a mature side that emerges from time to time. It is a charming combination.

Ex’s description (by Baek-hyeon): Hyun-ji has clear, bright eyes, and I still remember the day I first met her. Her pure gaze and gentle smile made me fall deeply in love before I even realized it. At my most painful moments, her care brought me great comfort. She also taught me, someone who had never known how to rely on others, what it felt like to be held in love for the first time. She is kind by nature, and I sincerely hope that after giving careful thought to coming here, she meets someone with a similar warmth of heart and lives a happy life.
