Although we know the boy as Kyouhei and the girl as Mei, their official names have been revealed to be Nate and Rosa (respectively)! Pretty good names in my opinion Behind the spoiler are two characters who are plot related. As Zowayix noted, these names play on the theme of “resonance” (kyoumei in Japanese) and their names sound like resonate.
Not much time left before the release!
