Haha, okay, this one’s set earlier in canon than I usually set things! Right after the Kokuyo arc, to be precise. This took longer than expected, but! Thanks for the Reborn prompt, it’s been a while since I’ve tried out his POV. *grins*
Tsuna and Reborn for 19: “You… You Used Me.” I assume you meant platonic. Anyway, since this is early canon and not an AU, featuring a Tsuna in Middle School, definitely platonic.
