Is this a symbolism for how Rin's the one giving that push to Hanayo and Maki to join Muse? If it is I'm gonna start crying now (its too beautiful ;_;)
Every pairing has potential. There's no such things like unmatchable couple, or at least that's what Touhou teach me.
This fanart came from that Cop-Phantom Thief UR set in LLSIF, which they look absolutely gorgeous together :)
