Love triangle

The Deal

(Sorry if this is bad, English isn't my first language,hope you like the first part)

It was morning and everyone was in the dining room for breakfast, Caspian was sitting between y/n and Susan, both knew they had a crush on him. After having breakfast y/n and Susan met in the woods to admire the nature and relax a little, chatting they also talked about their crush on Caspian.
-"Let's make a deal,let's see who wins his heart first"
Y/n says.
-"Ok!"
Susan replied, and then they shook hands.

Later Caspian was checking on the horses and   y/n noticed it,immediately she catches the opportunity to go and talk to him.
- "Hey! How are you?"
-"I'm good!" said Caspian .
And like that the two talked for hours until Edmund called them to come for dinner.

The next day while Susan was archery training Caspian was watching her, Susan threw an arrow at the target and centred it.
-"Wow,you're really good at archery!" Caspian says.
-"Thanks! Want me to teach you?" Susan says.
-"Sure! I wouldn't mind such a pretty girl teaching me"
Susan blushed a little but then she started to give tips and teach Caspian how to use bow and arrow.
After a bit of time y/n passes by and sees Susan and Caspian together, she suddenly feels a pang of jealousy but she knows she can't do anything so she decides to go back to the castle where her and the pevensie's lived.
