On the fifth episode of "To The Beautiful You," Koo Jaehee went to the swimming pool after receiving the message from Kang Taejun. However, the message wasn't from Taejun.

Kang Taejun asked Cha Eungyul where Jaehee was, and he asks whether or not he called Jaehee to the swimming pool. At that moment, he realized that someone was aiming for Koo Jaehee to put her in danger.

Both Taejun and Eungyul went to the swimming pool, and at that moment someone pushed her in to the pool.

She could be saved by Taejun and Eungyul. However, she needed an emergency CPR. Cha Eungyul couldn't process CPR because of his feelings towards her. Taejun processed CPR, saving Jaehee.

After the alcohol kiss, Sulli and Minho's second kiss scene was revealed. Also, the hinting of Lee Hyun Woo's jealous side in this scene raised the anticipation for the story.
