Daeun doesn't have a good relationship with her older sister, Yerin. She would often fight with her sister, but it doesn't mean that she hates her sister. Daeun is the opposite of her introverted sister. Daeun is an extrovert and has a lot of friends.

She didn't know when it started, but you were always in her mind. She would constantly think of you and she would constantly count down the time until she gets to see you and spend time with you again.

Daeun had been struggling with a particular subject lately so she decided to ask for your help. Now, she was sitting beside you inside her room while you taught her the subject she was struggling with.

"Ah, I get it now."
