Trunks Special piano song?

[CashMane]

I'm rewatching the Japanese version of the Trunks TV special, and I'm curious if anybody knows the song playing on the radio in the scene immediately after the last eyecatch 3 years after Gohan's death. It's the scene where Bulma and Trunks are talking while the time machine is being worked on before being interrupted by a bulletin of #17 and #18 attacking. It's a very pretty, soft piano melody that sounds kinda familiar, but I haven't found it anywhere. Does anybody know what I'm talking about? Is it an unreleased track?

Very short diegetic cues like music on the radio, muzak etc, were often written just for the scene or edited fragments of longer cues. It's very likely an unreleased track.
