SBS drama "To the Beautiful You" f(x)'s Sulli and SHINee's Minho couple will finally get a CPR kiss scene.

On the episode scheduled to air on Wednesday, Minho and Lee Hyun Woo rescue Sulli who falls off of a diving board and falls unconscious. Minho will attempt to use CPR on an unconscious Sulli at the pool.

The pictures show the sheer shock and panic on Minho's face which only heightens the anticipation factor as well as the romantic love lines, indicating that Minho's heart is really indeed opening up to Sulli in a lot of different ways. This is their second lip lock since Minho's drunken habits back in the second episode.

However, unlike Minho, Lee Hyun Woo is unable to actually put his lips to hers for the CPR. Both Minho and Lee Hyun Woo dive in to save her at the same time but Hyun Woo moves over for Minho to actually administer the CPR because he actually couldn't do it. As audiences begin to expect fast advances on their love stories, the Sulli-Minho-Hyun Woo love triangle is raising curiosities in viewers.

The CPR kiss scene was filmed at a pool in Suwon on the 26th for an hour. Minho and Sulli, thanks to their great relationship and teamwork, completed the scene without any bad takes. On set, Minho was spotted consoling Sulli, who can't swim, and was definitely a reliable male partner for her. When Sulli began to get scared before going in the deep parts of the pool, he told her how to breathe and told her that if she is in trouble, he'll save her. Thanks to his reassuring words, she was able to enter the water and finish the scene relatively easily.

Both Minho and Lee Hyun Woo showed off their masculinity and athletic side by filming the scene without the help of any equipment at a pool with depths over 5 meters. Though the risk factor was high, there were stunts on standby but the two of them, who started swimming at a young age, was able to do everything themselves.

The production company said, "Sulli and Minho are showing increasing teamwork as the days go on. The love story will become clearer now that Minho knows Sulli's true identity but Lee Hyun Woo will also start to really grow feelings for Sulli."

"To the Beautiful You'' 5th episode will air on Wednesday.
