Sulli and Minho are becoming more romantic. 

On the Wednesday episode of "To the Beautiful You," Tae Jun (Minho) gently hugs Jae Hee (Sulli). 

That day, Hyun Jae (Kang Ha Neul) had compromised Tae Jun's bike in an attempt to injure him before he fully recovered for the National qualifications. However, Jae Hee had noticed these things and had taken Tae Jun's bike instead in order to save him. As Jae Hee feared, the breaks were broken and she was barely saved by Eun Kyul (Lee Hyun Woo), who was in turn, injured trying to save her. 

Tae Jun realizes what she did for him and he hugs her from the back suddenly and says, "Thanks, I owe you a lot."

Jae Hee freezes on the spot but Tae Jun says, "Don't ever do it again. I don't want you getting hurt because of me."

At the end of the episode, Tae Jun is given bad news that his father collapsed.
