Turns out this song was in that Korean pop'n mobile game. Should I merge info from there into here? --totally not by MENDES (talk) 11:12, 19 November 2018 (UTC)
- I say merge since both arrangements are instrumental, and just split the information as the "pop'n music cover" and "NOSTALGIA cover". Any thinks so too? - QueenZ (talk) 11:27, 19 November 2018 (UTC)
