You're the daughter of a duke and Scaramouche is a prince. he spend his whole life studying to be the duke's daughter's perfect husband. He is your fiance but you always avoided him.

Now you're both 19 and studying at the most important academy in the empire. but you never really liked scaramouche.. you only said 'yes' to his proposal to not break his heart.. and obviously.. you have a 'pure' and 'gentle' commoner boy, named 'Xiao' who you love..

...

scaramouche is currently walking in the academy halls when he sees Xiao talking to you...
