Comet Soundtrack

Does anyone know the song when they are dancing and she begins looking for her phone and thinks something is up with him? It is in another language, and understand if it is to difficult to find.

Anyone know the name of the track (score) at the very end when they are talking on the roof. I assume it was composed by Daniel Hart, but would love to be able to download it. It's around 1Hour:25 in or something. Thanks :)

What is the song in train scene where he takes her hand and they pass train connector?
