'Twenty Five, Twenty One' Episode 13: Things Get Awry Between Na Hee Do and Baek Yi Jin

After they shared a chaste kiss to welcome the new year, Na Hee Do (Kim Tae Ri) and Baek Yi Jin (Nam Joo Hyuk) haven't seen one another since.

Despite that, they both know that something shifted between the two of them.

In "Twenty Five, Twenty One" episode 13, the two confused young adults try to find answers to their unanswered questions about love and its consequences.

Meanwhile, Yi Jin and Coach Yang (Kim Hye Eun) bump into each other and bonded over beer and soju (South Korean alcohol).

Coach Yang Warns Baek Yi Jin To Keep Distance

While drinking, Coach Yang shares her own story and how she and Hee Do's mother, UBS reporter Shin Jae Kyung (Seo Eun Kyung), ended their friendship.

Like Hee Do and Yi Jin, young Coach Yang and Shin Jae Kyung were a gold medalist fencer and a rookie UBS reporter.

Through their connection, they became close friends and shared many great memories together. However, because of the nature of Shin Jae Kyung's work, she was bound to hurt Coach Yang even if she didn't intend to.

Coach Yang then warns Yi Jin to keep his distance from the young fencer to avoid the same path they took.

Na Hee Do and Go Yu Rim Fight For the Gold

After their three-month suspension, Hee Do and Go Yu Rim (WJSN Bona) come back to the fencing field to fight for the gold one last time as Tae Yang High School fencing team.

Since their suspension, the two became rusty. Hee Do and Yu Rim performed poorly, which frustrated Coach Yang.

Little did she know, the two were burdened by the wavering feelings inside their hearts. Hee Do was worried about Yi Jin, and Yu Rim was torn between going to college or playing fencing as a job.

Thankfully, the heart-to-heart talk between them helped to boost their morale and enthusiasm.

At the end of the competition, Hee Do and Yu Rim's team bagged the gold and made Tae Yang High School proud.

Na Hee Do and Baek Yi Jin Gamble Everything For Love

When Yi Jin was warned about their proximity, he thought that it'd be easy to avoid Hee Do.

But when the fencer comes to his arms voluntarily, his heart wavers, especially after Hee Do confesses how much she loves Yi Jin.

Yi Jin didn't want to be unfair so he decided to gamble everything and create beautiful memories with Hee Do.

He kisses Hee Do with longing, despite the tears falling from their eyes, and swears he'll just cross the bridge of consequences when he gets there.
