Most caring person you will ever meet always putting others first and looking after everyone. You’ll be lucky to have a fionn in your life because he will always look after you. Fionn often doubts his self worth and will need reminding of how amazing and loved he is . Fionn is incredibly good looking but most importantly is incredibly kind ,looks are just a bonus.
I’m so lucky to have fionn in my life he’s the best thing that’s happened to me.
