Oh My Girl's Arin's stunning transformation has succeeded.
On the 11th, in the first two episodes of the Wave original drama 'S-Line,' which were released, Arin appeared before the audience with a completely new face, completely erasing her existing bright and fresh image.
In the drama, Arin's character 'Hyunheup' is a girl with a special ability to see the red line, known as 'S-Line,' that connects people who have sexual relationships. However, because of this ability, she transformed perfectly into Hyunheup, a high school student who has lived disconnected from the world. She depicted the character delicately and realistically, drawing attention with her deepened performance as an actress.
▲ Dramatic external change, delicate internal performance… completely immersed in 'Hyunheup'
The first thing that caught attention was Arin's external change. Cutting her trademark long hair drastically, Arin appeared with a short haircut, completing the character's dark vibe with near-bare face natural makeup and monochrome school uniform styling.
What is most impressive is the change in her voice and speech pattern. Instead of her previous bright and lively high tone, she delivered lines slowly in a low, dry tone, convincingly expressing the disconnected inner world of the character 'Hyunheup.' Her clear gaze and restrained emotions also captured the character's complex emotional lines delicately, drawing attention as she completely immersed into the character.
▲ The central axis of the story 'Hyunheup'… A thriller narrative led by Arin
'S-Line' is a unique thriller that unravels forbidden human relationships and hidden truths within a fantastical setting. At the center is the protagonist 'Hyunheup,' who is a key figure driving the story.
Arin carries the weight of this character solidly while delicately acting out a broad spectrum of emotions such as inner turmoil, loneliness, and wariness towards others, increasingly building anticipation for the stories that will unfold at the core.
Additionally, viewers are reacting positively not only to Arin's perfect transformation but also to her potential as an actress, proving real growth. Immediately after the release of episodes 1 and 2, enthusiastic reactions have continued with comments like, 'Her acting tone and gaze have completely changed,' 'I have never seen this Arin before,' and 'The immersion is incredible.' Arin's bold challenge as a new character and the growth and narrative of Hyunheup she will portray are also receiving attention as another point of interest in the upcoming story.
▲ Arin reborn as a 'real actress,' the future is even more anticipated
Through this work, Arin has proven her potential and growth as a full-fledged actress, surpassing the title of 'acting idol.' Despite the daring challenge, she has completely immersed into the character, and expectations for Hyunheup's activities in the unfolding story are even higher.
Meanwhile, the Wave original drama 'S-Line' is a fantasy thriller that begins to reveal forbidden desires and hidden truths as the red line, known as 'S-Line,' appears between people who have sexual relationships. The drama gained attention as a winner at the 8th Cannes International Series Festival in 2025, with episodes 1 and 2 released on the 11th at 11 a.m. Subsequent episodes will be released on the 18th and 25th, two episodes each, totaling six episodes.
