The conflicting memories of Kim So Hee and Chae Jong Hyeop are drawing attention as they bring about thrilling changes.
The new tvN Mon-Tue TV series "Is It a Coincidence?", scheduled to premiere on the 22nd, will feature
A teaser was released showing Lee Hong-ju (Kim So-hee) and Kang Hoo-young (Chae Jong Hyeop) each remembering their 19-year-old years in different ways.
The memories of passing each other in the same space, the moment when they were 19 years old that only they know stimulates the sensibilities of first love.
This has raised curiosity about Kang Hoo-young's first love. Lee Hong-ju gives love letters to Kang Hoo-young wherever she goes, such as in the hallway, in the playground, or in front of the toilet.
Hong-ju is a girl who is serious about love, has no spurs of the moment, and rushes ahead without thinking twice. "I'm here to confess. Let's go! For love," Lee Hong-ju's confident declaration is the image of a 19-year-old girl who is heading straight for her first love.
However, 29-year-old Lee Hong-ju has changed. She has become a "love skeptic," to the point of dismissing even her first love, which was once innocent and honest, as pathetic and childish.
But when Lee Hong-ju meets Kang Hoo-young, who remembers her from when she was 19, she experiences a thrilling transformation. Kang Hoo-young's words, "You're worried about me now, aren't you?"
It seemed to awaken the love cells in Lee Hong-ju's heart rate. What exciting changes will come to Lee Hong-ju?
The teaser video for Hooyoung shows 19-year-old Kang Hooyoung in Lee Hong-ju's memory.
Behind the face of 29-year-old Kang Hoo-young, who smiles so brightly that it brightens up the world, Lee Hong-ju's voice says, "He doesn't smile like that," changing the atmosphere.
The 19-year-old Kang Hoo-young that Lee Hong-ju recalled was like "a kindergartener who had no humanity and was only good at brains." It's clear that Kang Hoo-young has never fallen in love with anyone, according to Lee Hong-ju's writing.
Unlike his memories, during his school days, he was always looking at one person. Kang Hoo-young treasures a photo of Lee Hong-ju looking fresh in her school uniform. Looking at the photo, he smiles at a memory that comes to mind.
Her appearance arouses curiosity about his first love. Kang Hoo-young's confession that she likes him raises questions about what is hidden in the time when they were 19 years old, which neither of them remember.
Meanwhile, tvN's new Monday-Tuesday TV series "Coincidence" will start airing in Korea at 8:40 pm on the 22nd (Monday).
