Hetalia dj - Puolukka

Pairing: Sweden x Finland

From Hikari_Kaitou:

Kid!Finland is frustrated that kid!Sweden won't let him join him in battle, and when Sweden tells him it's because he's not strong enough, Finland throws himself into training. Then, in present day, an over-worked adult!Finland makes a wish on a shooting star to return to simpler times. This results in him switching places with his kid self. This installment follows what happens to kid!Finland with adult!Sweden.
