The feeling of butterflies dancing through their hearts fill the both of them, but it also leaves Hyejoong with a dreadful feeling. As much as she wants to enjoy spending time with Taeil, him being the awkward dog lover he is. She's afraid that history will repeat itself, that they will end up fighting.

Then she'll be left alone.

Taeil is dealing with his own struggles, he accepts that he has fallen for Hyejoong. He still feels like he's betraying his first love, even if she never loved him.  At the same time, he wants to make sure she didn't get hurt, he wants to shelter and protect her.

They both don't want to be alone, but they're also afraid to depend on the other.
