Meanwhile, Lee Jong-suk will play Cha Eun-ho, a rising writer with many best-sellers and also the youngest editor-in-chief in the publishing industry. Kang and Cha start out like siblings but viewers will see their relationship develop.

During the press conference, Lee Jong-suk was asked what it was like working with Lee Na-young, as he has said she is his ideal type in the past.

“I’m a ‘successful’ fan,” Lee said shyly, adding that he dreaded the question, which sparked laughter at the venue.

He told the press that the show would be like a gift to fans because he is likely to enlist in the military this year.

Starring in a rom-com for the first time, Lee said that he wanted to show what fans might like and that acting opposite Lee Na-young helped him to better play his role.

In the process, he has realized it is not an easy task to film a 16-episode show based on a story that centers on emotions between people.

He added that the only problem with acting opposite Lee Na-young is that he blushes while filming with her.

Jung Hyun-Jung, the writer of the show, who closely followed the publishing industry to better understand the field, hopes the show will be an opportunity for viewers to look back on their relationships.

“Relationships between people have become cooler in real life. Friendships and relationships don’t turn people’s lives upside down.

“I would like people to contemplate how we look at relationships between each other.” she said in a written statement.

The new tvN series will air at 9 p.m. on Saturdays and Sundays.
