Four weeks later...

Krystal blew the cake and everyone clapped.Not much people were there just the close ones including Naeun and her father.Kai's father was in a wheelchair that Naeun pushed.Kai was getting refreshments and was watching Yoonbaek and Krystal laughing from the corner of his eye.He tried not to make his attitude obvious.The feeling inside from seeing the two happy made it hard for Kai to swalllow up his food.

Everyone was enjoying so Kai tried his best to enjoy as well.Naeun saw him from afar sitting alone so she went to him and sat beside him"what's up?".

Kai smiled"It's bothering me,the fact that she can't remember me".

Naeun sighed"Oh that...I don't know anything about relationships but as your sister the best advice I can give is to never give up on Krystal.If you really love her you're going to do your best to win her heart again and also for her to remember you".

Kai smiled"You're such an expert".

"I'm building up my knowledge of love before I fall so then it won't hurt as much when I fall"replied Naeun.

Kai had teary eyes and he looked up to try and make it go away.Naeun punched him lightly on the shoulder"What's this,oppa crying?".

Kai smiled and wiped his eyes"I'm not crying,it's my condition gorahendroxis".

"Like that actually exists"replied Naeun chuckling.

Kai was walking around the garden when he saw Krystal sitting by herself on the bench.He took a deep breath and sat down beside her.Krystal turned around and looked at him.
